Right now our Process Controller exists for two primary reasons:

1. fork() misbehaves for large processes on some OSes, causing leaks or crashes
2. 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.
