sysVile IPC was positively hostile; a bolt-on that was very badly engineered.
the message queue implementation seemed to been have done by someone
who didn't understand queues and/or sleep/wakeup.
the shared memory was extremely non portable. where would you like to
stick the segment in your virtual address space? think of a random number,
a large one, but not too large and make sure it's aligned.
rfork make some things very easy.
