I got it to crash a couple of times.  Per your suggestion below, this
was in a case where Allegro returned a NIL value for a socket.

Not really.  BEIRC got all bollixed up because I was already logged into
freenode using my usual nick.  It doesn't seem to rollover from the
prespecified nick that happily.

I will see if I can replicate the behavior.

Should usocket return nil in this case, or raise an error?
