Thank you Kent, that's great to know.

There seems to be legacy magic in there, or hooks to support systems which were planned but never implemented. For example: createProcessId has a loop which waits for the value from generateControlTime to stabilise. However both the Linux and non-Linux versions of generateControlTime do nothing except set ctl_time=0. Similarly, ProcessId::confirm just sets true.

This is all something to do with process "birthdays". Perhaps the idea was to run on a system which can tell you when process IDs are being recycled?
