Yes, there is many such one-time memory leaks in Squid where Squid
allocates some memory on startup but never frees it on shutdown.
There is little to be gained from spending lots of time on getting
rid of this type of memory leaks as the memory is automatically freed
when the application (squid) terminates even if not explicitly freed.

The memory leaks which matters most for Squid is the leaks related to
normal processing, i.e. the kind of leaks which can leak more than
once during the lifetime of Squid.
