Description Michael Catanzaro 2015-09-15 19:18:41 UTC 
When I close Boxes (using the close button in the header bar, or Quit from the app menu), the Boxes window often hangs for 20-30 seconds before it disappears. The window should instead disappear immediately, and whatever shutdown work is required should occur in the background.

At first look, this seems like a gtk+ issue:

https://git.gnome.org/browse/gnome-boxes/tree/src/app.vala#n267

As you can see in that code, we first hide all top-level windows and then call quit *in idle* that calls shutdown, where we suspend all machines.

Ok, I think I know what's going on. The gtk_window_hide() does not work sync and shutdown() seems to be called immediately after quit_app() returns, without getting into main loop. As part of shutdown, suspend_machines() is called and that uses a private GMainContext so we never get back to main_loop until that function returns. I'll see how I can fix this..
