No worries, you hit the right target here ;-)

We don't have a sync version of the unmount operation because normally
unmount operations will need time (and maybe even user interaction, if  
you
use g_mount_unmount_with_operation, which you should be doing).

The (un)mount operation itself is done in the background (most likely
in a thread) but since GIO uses GSimpleAsyncResult internally the  
callback
will be called in the thread default main context (by using a  
g_idle_add).

I guess the easiest thing to do is to just move your "logic", i.e. the
operations what you wanna do, into the callback.

Not sure that was very helpful,
