A precise answer? A lot! :)
I'm currently porting unity to use a GSource wrapper (glib::Source) I
wrote to be more C++ friendly, (even if it could lead to some
overhead, but it's pretty simple and it gives development
benefits...). However, if you just try this branch
lp:~3v1n0/unity/move-to-gsource-wrapper adding some debug bits into
UnityCore/GLibSource* you'll notice how many sources we use,
especially on Dash Initialization.

Currently glib::Source is very simple and I've only designed it to
wrap the glib struct, but probably we could improve that also to be
reused.
