Apparently something changed in SBCL between 1.0.4 and 1.0.19.
Previously only the last established handler per fd would be called, now
they call all handlers.  As a consequence, read-char-no-hang may now
hang if we have a fd-handler on the same fd.  (It hangs in unix-read
inside a without-interrupts.  Bonus points for that feat :-)

Should be no longer be an issue for CVS SLIME.
