Source of memory leak in mod_proxy?

I just got a bug report that that the rewrite of ap_get_client_block() has
introduced a memory leak.  Problem is observed when putting a large file to
the server via webdav. Replacing the 2.0.40 implementation with the 2.0.39
implementation (on a 2.0.40 code base) eliminates the problem. I do not have
time to investigate this now. I can take a look tomorrow or perhaps this
evening if no one wants to pick it up.
