As I said, support 'pthreads'.  Code along the spec, not the
implementation.  If you have a bad implementation, use the non-threaded.  I
never said it would be threaded, just that it's something that has been

We take 0.1% at the moment.  If you have a decent thread implementation,
you won't have much overhead.  Most may be suboptimal but that doesn't stop
people from coding it.  Many people consider Windows 95 suboptimal but code
for it often.

The point is that you could.  Aiming to keep it that way keeps out much

If you have little memory, your OS will swap to disk for you.  If you have
a slow processor, you'll run slower.  When you have a lot of memory, your
OS will cache for you.  When you have a fast (or multiples of) processor,
you'll run faster. What does CircleMUD have to do?
