What I'd like to suggest is to add some safety feature to the Torch 
application, that would automatically turn off the flash diode after a certain 
amount of time, as to prevent overheating.

Why?

Flashlight died on my HTC Desire with CyanogenMod 7.1.0 stable too, but I guess 
it was my fault, because I forgot to turn the Torch off, before laying my phone 
on a desk, backside down of course, so I didn't notice the flash diode was 
still turned on. The high brightness option was turned off. After an hour or 
so, when I picked up the phone I noticed, the torch application still showing 
the bulb graphic as on, but the flash diode wasn't lit anymore and backside of 
the phone around the flashlight was very hot. The diode overheated and died. So 
the flash in camera application wouldn't work too, of course.

It was very cheap to fix it though. You can order another flash board on ebay 
for a few bucks and the tools needed to open the phone and replace it are 
usually included in the price. It's really a simple job I did it in less than 
10 minutes, there's no complicated action (like soldering or something) 
required, after removal of plastic phone cover with the help of the tools you 
get with the board, you just detach the old board by hand in install a new one 
to the connector.

It was my fault, for leaving the phone on, but the application didn't warn 
about overheating if the higher brightness option wasn't turned on, so a 
"stupid" user assumes that the diode won't die with the higher brightness 
turned off. It's true that maybe it overheated just because it was facing the 
desk surface so there wasn't enough air around the diode to cool down, but 
backside on a desk is probably the most usual place a user would put his phone, 
so many users can do the same stupid mistake I did.

But I think the Torch is still a nice application, I spend a lot of time under 
desks connecting or disconnecting computer cables and such and it's really 
handy to have my phone with the Torch application so I can lighten up those 
darker corners.
