Brandy,
Thanks for the info. That is very good to know. One thing that is
'busted' in AOLserver is the ability to provide threaded generic
servers. I would like to build this in for various reasons, so it looks
like the socket/fileevent method might be the way to go, and just forget
about threads.

For those who don't know, ns_socklistencallback runs in a single thread,
no matter how many times you call it with different ip/port
combinations. If any client connection blocks, everyone else stacks up
waiting.

Last week I started working on a shared 'Network Variable' server. Not
wanting to write any more C level code, I had to use
ns_socklistencallback to receive an ip/port number to dial back to, and
start a new thread on the listen server to dial back the client, which
had setup a server using ns_socklisten. While this worked great, I ran
into another issue: when a connection thread finishes with a connection
it forgets about any open fds, so the connection is only available for
the first connection. :(   So it looks like another project will be to
setup a module which allows persistent tcp connections, probably similar
to nsdb, but working with arrays instead of ns_sets.
