Please file a bug report with a backtrace of the fault..

Also, if you find a Squid which jumps to 100% cpu again, please run
"squid -k debug; sleep 1; squid -k debug" while it's consuming 100% cpu
and then file a bug report including your cache.log output.

Probably not a bottleneck but a problem somewhere.
