I've done a lot of work on Danga::Socket and Perlbal in the past few days
to address:
-- use IO::AIO (which is portable, unlike Linux::AIO).
-- unit test for Perlbal's webserver mode (used by MogileFS)
-- work correctly on 64-bit Linux
So I suggest everybody having problems go use the latest versions in cvs.
