Adding APR dev list:
IMO, httpd should expect APR to "do the right thing". If APR
isn't doing that, then it's an APR bug and needs to be fixed/
addressed within APR.
All this implies that the atomics code in APR needs a serious
review and update.
We should also look into leveraging what we can from stdcxx
(https://svn.apache.org/repos/asf/stdcxx/trunk/src) as well
as OPA (https://trac.mcs.anl.gov/projects/openpa/wiki/FAQ).
Also, IMO, the default should be non-portable

I think using the apr_atomics functions meets those goals the best. The downside are for those systems that are running 32-bit i486, i586, i686 systems where the default APR configure setting was not overridden for atomics. There may be i686 servers still out there using 32-bit web server, probably memory-constrained systems like VPS hosts; the question is have they overridden the APR default configuration or not.
