IIRC, APR makes the determination to pull in the thread-safe libraries.
APR will always pull in anything required for threads regardless of
the MPM.  So, I believe we're *always* thread-safe.  If you use 
--disable-threads, worker MPM won't compile.

This is a pet peeve of mine - if you are running prefork, you
should always add --disable-threads for another 10-15% performance
improvement.  But, on Solaris, worker squashes prefork.  -- justin
