Mutexes and the like are not simple tools to use.  I have my first
multithreaded code that I ever wrote.  I wrote it merely by looking
up what the functions did - I hadn't yet had any class or formal
training with multiprocessing.  The code is, by and large, horrible.
It took a design class and a bunch of code writing to finally start
doing threads and processes right.

If someone just wants to write a mud for the fun of writing a mud,
then there's no reason to use threads when you can do without,
especially if you don't already know the ends and outs of
multiprocessing.
