Well, I don't know if anyone is working on it or not.  And I'm not at all 
sure if the problem lies with unionfs, or with my disk drive, since this 
is the same drive that occassionally only transfers 8191 bytes of data 
for an 8192 byte request!  I've just completed moving nearly all of my 
stuff onto a different drive, including both the upper and lower layers 
of my union mount, so it will take a week or three for me to feel 
comfortable saying that I have or have not solved the problem.

Then again, since these strange panics only occur during the cron job, 
and almost always while I've got some sort of build running at the same 
time, maybe what I'm seeing is the "multi-access" problems that others 
have reported with unionfs.
