It fixes the hang, but it still doesn't work 100% correctly.  Try the
following test program.

BTW, do you run any fs test suits?  All these were caught with one I use
to quick test fuse (it's in the fuse git tree(*) under the "test"
directory).  But I guess others like LTP would catch these as well.

Thanks,
