Something I'm missing?

I just upgraded Scarab to use Tomcat 4.1.24 and now when I ctrl-c it on OSX
to kill it, I get the following stack trace printed to stdout...

Nice to see you back on tomcat-dev :-)

I think I fixed that in the main tree, next release of the connector
should have the fix.

The code tries to unlock the socket ( which is blocked in accept )
by making a new connection. In some cases it seems the unlocking/close
is different - so we need some extra checks. AFAIK all the errors
are harmless.
