[optical drive auto-load] [patch request] Add debugging messagesto optical drive auto-loadtray.

There is an application hammering the first optical drive and I'd like
to discover it's pid and perhaps the name of it's executable. The
application triggers the drive's auto-loadtray and causes this lovely
feature to become unusable. :(


I'd like a patch that I could use for testing that would indicate the
application(by pid or path) that causes any of the drives
auto-load/eject features. These events should be rare enough on every
system to always be logged at an information level.

Please CC me in responses.

On a related note the drives I have require a delay(about 7 seconds)
from the time the tray is indicated as loaded to when the drive is ready
to process read requests. This causes mount to fail, I've used 'eject
-t $drv; sleep 7; mount $drv;' to counteract this.

The drive is Brand: LG Type: BlueRay Name: Super Multi Blue Model: CH08
