Determine when an exec command is finished.

[JethroMV]

Hi all,
The tests don't show a way to determine when a command exec'd in a pod returns, or what it's return status is.

Is there any way to a determine this? Or could it be implemented?
Our workaround at the moment is reading maybeStdout & maybeStderr and waiting for it to stop producing for n seconds. Or to echo out some marker after any command runs so we know it's finished.

Thanks for any help.
