I have multiple processes running threaded applications which would like
to do 64bit wide atomic arithmetic, which if I understand correctly can
only be achieved either via IPC (having a master process to do all the
stuff) or sharing a mutex somehow. And as far as I understand, mutexes
are process-local by default.
