Julian Elischer f4bb4fc8f3 Completely remove the code for single threading the mainline fork code. 
Put in a little comment explaining why it went away.
Re-enable it in the case there an exisiting process is just splitting
off its address space and file descriptors.
(I donpt think anything uses that code but it needs some sort of locking
and this does the job.
