The 100%-CPU-GUI-lockup-problem (with alt-. not responding) occurs every
other week or so in my Swiki. No Morphic, no PPP, no Sound, just plain
Squeak 2.2 / 2.3b. The interesting thing is, nobody outside notices it
because the *server is still serving*.
IMHO it's a network/socket/*ConnectionQueue* problem that occurs at some
rare conditions. I think it could be solved with accepting sockets -
*please* put it into 2.3 (even if the Mac would implement it using the
ConnectionQueue stuff :-)
