I think the idea was to have the following options:
 * cache using memcached (Cache::Memcached installed, and memcached on)
 * cache using filesystem, perhaps size aware (with limited cache size)
 * no caching

It is quite possible that one would want/need gitweb caching, but
either does not want hassle with memcached, or memcached is not
feasible (for example memory starved machine).

This should be fairly easy, just modify git_cmd() to count number of
calls.

And this I don't think it would be easy.
