Hello,
I own a bazillion-in-one USB card reader which registers 4 different
devices when it is plugged in. As Murphy would have it, the slot which
actually contains my xD card is always registered last (or
second-to-last) by udev. Due to usbmount's global lock, this leads to a
long wait:

That's one minute from plugging in the card reader until the card is
mounted! :-(
The solution to this problem is to have one lock per device, see the
patch at the end of this report. Using it, the filesystem is mounted
immediately:
