I wish you were right on that, because if the system had locked up when one 
disc failed I wouldn't have had a client contact me late last week when the 
second drive in their 3-drive RAID-5 failed.  This was one of their 
development boxes (we're only responsible for their production machines), and 
either the software RAID alert never got to their mail server, or it was 
ignored (the system seemed correctly configured to e-mail an alert on failure).

As we've said before, it really depends on a number of things like the 
controller and how gracefully it handles and reports failures to the software 
RAID.
