Indeed, it doesn't solve the original problem at all, because you just
have to keep dispatching randomly and hope for the best.

Ugh.  I really don't like the look of that; would be nice to have a
wl_display_dispatch_some_subset_of_pending(), which would return
failure / dispatched everything / still stuff left to dispatch.  But I
worry this takes us into libdbus API design territory ...
