And here is the crux of my problem.

Threads are great, but 1) Linux doesnt have them unless I use pthreads.(*)
2) Pthreads hasnt made to EVERY platform yet...and it seems like thread
implementations aren't standard yet...

So..I'm thinking since most systems support shared memory, that would be a
logical way to go.  Sort of kludge-ish...but I think it is something of the 
right thing to do.

Correct me if I'm wrong here..

(*) Yes, I know Linux 1.3 has clone() slowly supporting threads..but I can't
base adding features to a mud where I might not have a development Linux
kernel on.  Then I have all these ugly reentry problems to worry about with
threads...course, I might have them with shared mem... :)
