I spent maybe an hour trying to get the info. No definitive answers
yet, but what's happening seems to be even weirder than I thought:

- gdb'ing the squid process (just an attach an a continue, nothing
else done) when this happens seem to make squid return to normal

- squidclient mgr:filedescriptors just returns an error message:

Assertion failed: (false), function GetAddrInfo, file Address.cc, line 689.
assert "false" at line 689
Ip::Address invalid? with IsIPv4()=F, IsIPv6()=T
ADDRESS: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1
/usr/local/sbin/ls-squid-filedesciptors: line 1: 4015 Abort trap: 6

- gdb'ing squidclient seems to also cause squid to return to normal

- cachemgr.cgi seems to eventually work, but when the listing is
returned squid has already magically returned to normal

I'm going to restart my Mac later when I can just let squid freeze
until the next morning. I'll see if squid actually will unfreeze
itself over the night or I'll get anything out of the file descriptor
listing.
