[lldb-dev] Tests leaving behind zombie processes on OS X

[Chaoren Lin]

Hi Greg,

The following tests leave behind zombie a.out processes on OS X after
finishing:

   - TestGdbRemoteAbort.py
   - TestGdbRemoteSegFault.py
   - TestGdbRemote_vCont.py
   - TestGdbRemoteSingleStep.py
   - TestLldbGdbServer.py

Since the parent is launchd, there is no way to remove them. Eventually our
OS X buildbot runs into a zombie apocalypse, and must be rebooted.

This seems to be a bug in launchd, since it should be reaping the zombies.

Is there anything we can do about this?

Thanks,
Chaoren
