I am sad to report that my attempt at multi-threading the current macro system did \
not succeed. However valuable lessons were learned in the process.

My previous approach of creating a couple of functions and placng mutexs on them was \
not sufficient. Each thread is going to end up needing it's own isolated macro system \
for the current system to work.

My new approach will be similar in some respects except that there will be thread \
specific versions of each macro, something along the lines of...

macro_x[tid][MACRO_NAME]

It's not a permanent solution, but I believe it will work and it's clean without \
requiring another refactor. Furthermore, it should port to the 3x branch without much \
trouble at all, just a simple search and replace.

I'll let you know how it works out.

Sincerely,
Steve
