All,

Added anothe valgrind log which core dumps. It seems the maildir driver is never releasing memory, so if you have a large number of messages (or very large messages) the maildir_fetch_msg will consume all memory. It also seems that the compression is a red herring, is only related in such a way that the out of memory condition is more likely.
Attached a --tool=massif valgrind run.
