Multithreading Segfaults :(

[Steven D. Morrey]

I've got the code complete for multi-threading the main event loop.

It looks like the system is now segfaulting at various rather random places, but they all seem to be related to macros.
First time it happened it was get_service_macros, next time was clear_volatile_macros.
It looks to me like the macro_x stuff is being accessed by multiple threads and we're getting a train wreck because of it.

Normally I'd just put up a mutex on all the places that use the macro_x stuff.  But it looks like it's used in 617 different places in code, thats a lot of mutexes.
I'll probably just put one on each function that deals with the macro_x stuff unless someone has a better idea.

Sincerely,
Steve
