kay.sievers@vrfy.org 2b41e68a08 [PATCH] replace tdb database by simple lockless file database 
This makes the udev operation completely lockless by storing a
file for every node in /dev/.udevdb/* This solved the problem
with deadlocking concurrent udev processes waiting for each other
to release the file lock under heavy load.
