Um ... Restarting Squid drops all the memory it has allocated, whether
leaked or not. Same as killing the process.

This sounds very much like something I saw back in the 2.6.31 kernel
last year. Any app that used a lot of memory or connections slowly
(relative) leaked RAM into the kernel space somehow. Only a system
restart or kernel upgrade to 2.6.32 fixed it here.
