unfortunately i'm not sure users will find it intuitive that
signal_connect() takes over the ownership as timeout_set_clousre,
but _foreach not doing so.
from a simple usage level, they probably want to be able to use
g_cclosure_new() inlined in all of those function calls, don't
you think? (and if they still do, while _foreach doesn't sink,
we'll silently leak closures all over the place)
