[Voyage-linux] udev & hotplug

[Gustin Johnson]

Simply put, I don't always have access to killall (I use other
hardware and softwaresuch as OpenWRT and some really constrained ARM
and MIPS boards).  psmisc is almost 1 MiB in size.  This has not been
a problem in the last few years but the code works, so I have not
changed it :)

killall -r would also work in cases where you need to be more
selective (python apps, java apps, etc.).

pidof I simply did not know about.
