I'll have a look tonight, but I think I fixed this problem in newer
usocket releases already. The newest usocket is 0.3.5. [After looking
at the list of releases at the bottom of
http://common-lisp.net/project/usocket/] I think your problem may have
been fixed in usocket 0.3.3. (But again, I'll look at it later -
tonight)
