The memory "leak" is probably just excessive growth of the dcache and
inodes. I'm working on the inode memory management, and will post a
patch for testing later today. I've implemented very simple dcache
pruning routine for micro-shrinking the dcache, and it works quite well
at controlling dcache and inode growth.
