[Buildbot-devel] Getting buildbot to kill all subprocesses

[Uma Sridharan]

The & is literal. I have 3 sleep processes seperated by & in a shell script.
When I run the shell script and do ps -e, I get 4 processes listed. shell
script + 3 sleep processes. When I do a stop build ( using os.kill(-pid) or
os.killpg(pid)) it only kills the shell process. Not the sleep processes.
