I also just got an assertion failure due to something in the startup
process. Unfortunately I lost it before digging further, but I think it
was the proc_exit() call in StartupProcShutdownHandler(). I'll try to
reproduce it to get more details. In any case, I'm a bit worried that
these assertions will cause quite a bit of noise. I think we'd better
concoct a plan for dealing with them prior to inflicting the buildfarm.
