All allocations done for a particular requests are freed as long
as the request is finished. The problem though is that OS
memory allocators rarely return freed memory back to the OS,
especially on Linux. You may try playing with allocators and/or
allocator options to make things better.

Note well that "spare" memory isn't really spare, as it can be
used by OS for file cache.
