Make udev re-process the rules database?

Is there a way to easily make udev re-process the rules database?

The scenario I found was when I was messing with rules that applied to
ttyS[0-3].  I would change a rule, and then I couldn't figure out how to
simulate a removal/insertion event to test the new rule.

Yes, I could use some udev tools to get a simulation of what the rules
would do, but that's not the same thing.  And, depending on what I was
changing, the simulation would not give me correct information about what
would happen.

I wound up doing a lot of rebooting... but is there an easier way?

	udevadm control --reload_rules

man pages are a wonderful thing :)

Echo "remove"/"add" to /dev$DEVPATH/uevent?
