How to make apache mempool work with valgrind?

[sc1801]

I found that valgrind is quite useful after several days using it, and
as far as I know,
to make valgrind work well with apache mempool (APR Libaray), it should
make some change in mempool source code, My question is "is there
already some APR patches to use ? and if so, where can I get it. And if
not,is someone else interested in develop one with me?"
