Hey, continue down that path and you'll be in iOS style cooperative-daemon
multitasking in no-time :) Which, while not bad in itself, DOES require a
substantial level of effort on part of the developer, especially, as
mentioned by others, if it's a port using funky event loops. That's why,
unlike in the case of iOS I do believe this call is not to be made by
*compulsorily* overcomplicated by the OS/daemons in our case.

I kinda would say this fits Shepherd's use-case (DBUS suspend/resume event
as trigger, SIGSTOP/resume as action), but considering how late I am on that
project I better keep quiet :)
