Description of problem:
I created a distributed-replicate volume & created 2 mounts. Removed all performance translators. 
On 1 client started, untarring ltp-testsuite in a loop & on another client started rm -rf of the ltp directory in a loop.

Got directory not empty error during rm which was fine. Stopped all operations & then reset the volume.

Next i tried removing the ltp directory. I got these errors:
rm: cannot remove `ltp-full-20091031/testcases/ballista/': Directory not empty
rm: cannot remove `ltp-full-20091031/testcases/kernel/syscalls': Directory not empty
rm: cannot remove `ltp-full-20091031/testcases/open_posix_testsuite/conformance': Directory not empty
rm: cannot remove `ltp-full-20091031/testcases/network/stress': Directory not empty


Checked the backend:
The first dht subvolume did not have any entries under ltp-full-20091031/testcases/ballista/ but the second subvolume had directories under it.

echo 3 > /proc/sys/vm/drop_caches on the mountpoint & `stat`d from the mountpoint. Found nothing. 

Therefore it keeps telling. directory not empty.
