[boost] RFC: Multithreading design constraints

It seems to me that having all these operations
(read/write/add/test&set/exchange) is a bit overkill. What's wrong
with just a plain old mutex (with lock/unlock).  Is there that much of
a performance difference to be gained?

Oh, and along the lines of Steve's comment about signaling locks, etc.
the notions of a semaphore and of a condition variable (both are in
posix threads) are certainly important... probably important enough to
be considered separately from mutexes.

Cheers,

Jeremy
