1.2b1 bug..

Ok. the fix on this has been a little stumped..

squid: comm.c:336: commConnectDnsHandle: Assertion `ia->cur < ia->count' failed.

Traceback below.

As near as I can tell, it's failing to unwind properly. It {tried to
connect, failed, did an ipcache_nbgethostbyname} x 4, did an
ipcacheRemoveBadAddr, and returned, but then the ipcache_call_pending
did the callback again (because it had been added 4 times without
being removed yet??), which promptly died because ipcacheRemoveBadAddr
had set ia->cur == 0, which isn't less than 0. :)

Ideas on a fix?
