[Mono-aspnet-list] Memory Leak in Generic Handler

I'm still working on this issue and have come across the following page...

As I'm using generic handlers I assume I'm adhering to this anyway, as I'm
writing the request stream directly to disk, unless it's JSON in which I'm
having to parse it of course.  The JSON blobs are tiny so shouldn't result
the memory leaks afaik.

Anyone else experienced this or have any work arounds?

Nick.
