> Right now our Process Controller exists for two primary reasons:
> # fork() misbehaves for large processes on some OSes, causing leaks or crashes
> # if the HC crashes, the PC can respawn it
> We have never (afaik) seen #2 happen.  We need to verify whether #1 is still true on modern JVMs on the following operating systems:
> * Linux
> * Solaris
> * IBM OSes
> * Windows
> * BSDs
> * Mac OS X
> Test by creating processes with large heap and lots of concurrent file descriptor activity while forking to see what happens.
