How to release apr_socket_accept memory pool

[GHui <ug...@gmail.com>]

I code a server with apr_socket_accept and apr_pollset_poll. But apr_socket_accept and apr_pollset_add take up the memory pool. I cann't release or clear memory pool. So it take up more and more memory. 
Any help will be appreciated. -GHui

Pools can be recycled in an aside list (or APR_RING), after being
cleared (which closes the socket), so that the next connections will
either reuse an existing/idle pool or create a new one (lately
recycled).
You may also use an apr_reslist of pools if you need synchronization
and native parameters to handle the pools' limits/lifetime in the
list.

This both ovoids leaks and becomes optimaly efficient once the maximum
number of connections have been reached (all pools are reused).

If do this, every connect need create a subpool, and clear mpool when close the connect.

Can you not solve that problem by using a subpool for those
functions?  That way you can give the subpool the lifetime
you need it to have, regardless of other resources that
prevent you clearing the parent pool.
