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?
