Thanks.. I missed that.. I've got some live code that is very similar to this
on a Solaris 10 server and the first thread to do a send hangs the entire
process since it ends up doing a poll() down in the bowels.. I do not have
a stackdump unfortunately since it's not on wired server (disconnected 
from the Internet)… I'll have to look at it closer to see if there's a disconnect
between it and this sample code.
