 Hi,
 I'm running a Buildbot who gets stuck in a step:

 - The command is run through a Compile step.
 - When it's done, the program quits normally (and it disappears from ps(1)
 output)
 - Buildbot doesn't detect program termination and keeps waiting
 - Eventually, Buildbot detects there is no output for a long time:
 "command timed out: 1200 seconds without output" but it's still stuck
 - Interrupting the build does nothing
 - The only solution I have is to restart the slave: "buildslave restart
 myslave"
 - We have hundreds of steps on different slaves, but only this one
 reproduces 10% of the time.

 The step runs a python/multiprocessed application (if it can make a
 difference)
