## Detailed Description

A GSource implementation that is activated by OS signals.

Caveat: if the process is receiving a lot of signals in a short period of time, it's possible that the sources will not be notified for all the instances of a particular signal. So this mechanism shouldn't be used for reliable event delivery.
