This may be what Martin Sperl is reporting in the squid-users thread
"squid: Memory utilization higher than expected since moving from 3.3 to
3.4 and Vary: working"

What I'm trying to get from him there is a series of mgr:mem reports
over time to see if any particular object type is growing unusually. And
mgr:filedescriptors in case its a side effect of the hung connections
Christos identified recently.

If we are lucky enough that the squid was built with valgrind support
there should be a valgrind leak trace available in one of the info and
mem reports. This will only catch real leaks though, not ref-counting
holding things active.
