e.g. for each of /sys/class/t*/*, write the name into a file
(/tmp/waiting) and write to the uevent... in a udev rule for events,
remove the line from the /tmp/waiting file.

Sleep until the /tmp/waiting file is zero bytes in size.


Ok, that's just as hacky as grovelling around in ps I guess, but at
least it has the advantage that there's no possibility of no udev
processes having been started by the next line of shell - which there is
with your example.

There's almost certainly a more elegant way, but basically mark the
events you're waiting for and wait for them all to come back.
