without the non-portable atomic code available and enabled in APR, this is 
going to hurt performance, right?  (more mutex operations performed in mainline 
path for the unlucky who use the non-portable atomics???)  is it noticeable?

the atomics in the pending apr-1.0-dev still leave much to be desired :(  no 
compare-and-swap interface even on common platforms such as Solaris/Sparc and 
AIX...  though Greg got c-a-s working on PPC yesterday; I'd expect AIX to be 
supported soon...
