I'm afraid this looks like a usocket problem and you should ask on
their mailing list.  Andreas Fuchs and others convinced me to switch
Drakma from trivial-sockets to usocket, and one of their arguments was
that trivial-sockets is unmaintained while usocket has an active
developer community.  So, you can now check if they were right... :)
