Description of problem:
From at least 60GB into a 220GB rsync over ssh retrieve, one CPU core is being
used at 99%-100%. This stays this way many hours after the big rsync has completed.

How reproducible:   Only seen once.

Steps to Reproduce:
1. using vnc to the actual machine.
2. start a script: essentially
rsync --bwlimit=10000000 --progress --stats -e 'ssh -p 30722 -i
/root/sshkey-mirror-offsite' -az
--exclude-from="/root/rsync-scripts/rsync-offsite-full-exclude.lst"  server:/
/home/mirror/server/>>$logfilename
3. Wait for the bwlimited dl to complete {first time sync}
4. tail -f $logfilename
5. gkrellm open viewing cpu+disk+network activity
6. top running.
7. nautilus  {always browse} using the 
  
Actual results:
When checked 60GB into the copy, noted that one core of the AMD AM2 dual-core
processor is consuming 100% CPU. The attachment contains a screenshot of the
gkrellm + top many hours after the rsync has completed.

Expected results:
Since the process is bw limited, and the network speed is much slower than both
the hard disk and CPU speeds, CPU should be rather unutilized during the
process, and should be completetly idle after comletion.

Additional info:
a. While web searching for bug, noticed that occasionally the CPU use jumps to
the other processor.
b. The machine was a FC6T3 install the previous day onto a software raid 1 on
750GB sata drives. The raid build for some of the volumes was continuing when
this rsync was started. As of writing this md2_raid1 process had completed,
however, it had taken: {sorted by cumulative cpu use}

c. The machine has vmware-server and server-console installed, and configured
for the running kernel, however, no virt machines have been created.
d. Trying to start a File Browser from the menu does not start it.

  however, nautilus was not used to initiate the copy (started the rsync script
from a gnome-terminal).

  however, gamin is not showing in top, but is running in ps:
