The issue is closed and I recently fixed a number of races (bf74797c69)
in the remote attach API that sound like exactly like the same error
that was mentioned in issue #9597.
As such I think this works, if it start flaking again we can revert this
or better fix the actual bug.

As it turns on things are not so simple after all...
In podman-py it was reported[1] that waiting might hang, per our docs wait
on multiple conditions should exit once the first one is hit and not all
of them. However because the new wait logic never checked if the context
was cancelled the goroutine kept running until conmon exited and because
we used a waitgroup to wait for all of them to finish it blocked until
that happened.
First we can remove the waitgroup as we only need to wait for one of
them anyway via the channel. While this alone fixes the hang it would
still leak the other goroutine. As there is no way to cancel a goroutine
all the code must check for a cancelled context in the wait loop to no
leak.

We were only splitting on tabs, not spaces, so we returned just a
single line most of the time, not an array of the fields in the
output of `ps`. Unfortunately, some of these fields are allowed
to contain spaces themselves, which makes things complicated, but
we got lucky in that Docker took the simplest possible solution
and just assumed that only one field would contain spaces and it
would always be the last one, which is easy enough to duplicate
on our end.

For the past two months we've been splitting system tests
into two categories: those that CAN be run in parallel,
and those that CANNOT. Much work has been done to replace
hardcoded names (mycontainer, mypod) with safename().
Hundreds of test runs, in CI and on Ed's laptop, have
proven this approach viable.
make {local,remote}system now runs in two steps: first
the serial ones, then the parallel ones. hack/bats will
now recognize the 'ci:parallel' tag and add --jobs (nprocs).
This requires some tweaking of leak_check, because there
can be umpteen tests running (affecting image/container/pod/etc
state) when any given test completes.
Rules for enabling parallelization in tests:
* use unique container/pod/volume/network names (safename)
* do not run 'podman rm -a' or 'rmi -a'
* never use the -l (--latest) option
* do not run 'podman ps/images' and expect precise output

...and remove one old skip() for older debian, but leave
two others in place and mark that they're still a problem.

podman-remote events are not flushed, so order is not guaranteed.
This results in CI flakes. Only on Debian, for reasons unknown.
Make the network-connection events test more lenient when remote.

convert the owner UID and GID into the user namespace only when
":idmap" mount is used.
This changes the behaviour of :idmap with an empty volume. Now the
existing directory ownership is copied up as in the other case.

There is no point in logging them, the directories not existing is fine
and expected and logging these by default when useing -dryrun just
causes confusion.

pasta doesn't switch to nobody when we already run in a userns so we can
use it there. The unshare package checks the same condition and returns
true even if uid 0 in this case so we can directly call this.

Instead of ErrVMAlreadyRunning use a more appropriate error.
Also improve the message a little bit.

The `RemoveFilesAndConnections` function is not being used, so its safe
to remove it and not carry unnecessary code that we need to maintain.
