While testing a fix I came across a deadlock which was caused by memory corruption. FUSE was a suspect, as fuse.ko had been loaded and unloaded at one point earlier in the test (no actual fuse tests were done). A test was constructed that loaded and unloaded fuse.ko under VM pressure. This triggers a page fault in the page daemon: http://people.freebsd.org/~pho/stress/log/fuse3.txt - Peter
