Description

After fusermount completes successfully, cfuse did not exit in these runs:

teuthology:~teuthworker/archive/nightly_coverage_2011-09-05/653
teuthology:~teuthworker/archive/nightly_coverage_2011-09-05/625

I killed the process manually both times - in the first case, cfuse was busily polling select(2). In the second hang, cfuse was waiting on a futex.
Currently, teuthology waits for cfuse to exit after unmounting. Perhaps it should kill it instead if there's been an error?

This is usually caused by leaked inode references. A full client log (debug ms = 1, debug client = 20, debug objectcacher = 20) should be enough to fix it.

This occurred again on the snaps workunit in teuthology:~teuthworker/archive/nightly_coverage_2011-09-21/372. cfuse was waiting on a futex. The log may provide a clue in this case:
