Hi Amos,
Is there any "definitely lost" record?

We seem to have tracked the major leak ( ~1MB per request) down to these:
mem_obj->delayRead(DeferredRead(DeferReader, this, CommRead(fd, buf,

I believe its the fact that CommRead is allocating itself a buffer via
xmalloc().
Is anyone else able to track this out please?
