run off and forgot all about it for a while), I couldn't even get the
socket to open. Hopefully, however, you're right on this. Later
tonight I will potentially try to set up an Apache + CGI PHP + xdebug2
and APD and see what I can find. If that doesn't work, I'll start
doing stack traces (I need the practice for my PHP extension writing
anyways) and hopefully whatever it is, we can fix the problem. If
anyone has any secondary setup where the future posting stuff is known
to fail, and would like to donate a bit of space for testing, it would
be greatly appreciated.

I know I modified a little bit of the sockets code, what I thought may
have been just for clarity at the time, but its been a while since I
looked at the cron code as well, so who knows? :D
