I don't have AIX 5 here, so cannot test, sorry.
But yes, it should definitely work.

There is a known possible performance improvement for concurrent sessions on
multiprocessor AIX machines. The now depricated "cs(3)" used for the AIX TAS
implementation should be replaced with fetch_and_or, compare_and_swap or the
like. I just haven't got round to doing a patch that I trust.
