If  it supports all the execution properties of mdev it would be perfect
for me to import it into nldev and make an nldevd, which  would  be  the
true replacement for udevd.

Try to cache the result of regcomp(). This will speed up things in large
trees. For being a competitor. When designing any replacement for udevd,
keep  in mind that due to that permission misdesign in Linux your daemon
has to manage some 10 thousand devices in  a  huge  server  in  under  a
minute.   This  can’t  be  done  linearly and is why udevd keeps a queue
of worker processes.
