Are you looking for bugs in your application or suspecting bugs in Apache?
And what tool is reporting your memory use?

There are parts of the subrequest that can't be destroyed until the main
request is completed, because they may be needed by the main request.
For example, response headers.  Or data on the output chain, which may
be buffered.

What happens when the main request terminates?
