Comment (by zooko):

 This is a serious bug. It is correctly marked "critical" in Priority.
 What's the next step? I think it is either to use a tool like [http
 ://tahoe-lafs.org/trac/pyutil/browser/trunk/pyutil/memutil.py?rev=218#L47
 check_for_obj_leakage] in a controlled deterministic unit-test style
 exercise of the SFTP front-end code, or else for someone to experiment
 with a live system and try to figure out what sorts of usage patterns
 trigger the memory consumption.

 Any other ideas?
