Possible memory corruption with FUSE

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:
