Yeah, seems there's some leaks (both in trinity and the kernel).
Oddly enough someone else emailed me about that this morning, which
prompted me to write up this: http://codemonkey.org.uk/2012/11/21/fuzz-testing-oom-killer/
Which is just part of the problem. There are other issues too it seems. Fun.
