In addition to this I would suggest making sure you have debug symbols
in your build
and capturing a core file.
You can do that by setting "ulimit -c unlimited" in the environment
where ceph-fuse is running.
Once you have a core file you can do the following.
$ gdb /path/to/ceph-fuse core.XXXX
(gdb) thread apply all bt full
This looks like it might be a race and that might help us identify the
threads involved.
