Or maybe a signal when an entry appears is sysfs?  IIRC, sysfs
supports dnotify, although I haven't tried it.  Have a daemon
watch a bus's sysfs directory for DN_CREATE|DN_DELETE.  Then the
kernel never need exec a program for plugging.

There's some worry about having too many RT signals queued up, but 
I imagine filling a pipe could be an issue too.

Jason, waiting bemusedly for links to /sys from /dev to replace
links to /devices from /dev...
