udev script causes race conditions with multiple lirc instances

Bug Description

When using a remote and a transmitter on the same box, udev will cause some (ugly) race conditions that result in very long boot times and occasionally will bring down the system. The udev script also notes some flaws when trying to handle two lirc instances.

Since the modules are loaded at boot time and configuration is driven through /etc/lirc/hardware.conf, the udev rules may not be required at this point.

Comments and discussion on this topic is encouraged. Confirmation of this problem would also be nice.

 Hi Andrew,

I wasn't aware of these race conditions. Could you elaborate a little bit with
them?
