That's a lot to ask for a simple script :)

Why not just pick one of those options and go with it?

Then do the 'sit and spin' method. That works for all of the above
options, right?

Please realize that this "behaviour" is not guaranteed at all. And in
fact will be changing in the future so that it is _not_ the way it will
work.

dev.d is called by the kernel, not your script. You don't have to set a
priority of when dev.d runs at all, it's not necessary.

What problems?
