I assume that's because if recv blocks then Emacs can't get around to
reading keyboard input, but I know very little about these things so
please feel free to correct me or clarify.

Not just prolonged, but indefinite.  I have yet to find a way to restore
these graphical sessions to normal operation, so for my intents and
purposes they have completely hung, i.e. I presume there's a bug
somewhere that results in recv waiting for a message it will never
receive.

Thanks,
