gnome-session-inhibit --inhibit suspend fails to inhibit suspend

[Marius Gedminas]

I want to run offlineimap and have the laptop go to sleep when it's done syncing my mail.

I run

    gnome-session-inhibit --inhibit suspend offlineimap

and close the laptop lid.

The laptop goes to sleep immediately, without waiting for offlineimap to do its job (which takes ~3 minutes).
