[Evolution-hackers] Re: bonobo_main thread ...

The extra mainloop thread makes programs that don't use the async api
possible, when they don't have another thread running a mainloop.



e_book_get_default_addressbook (&book, NULL);

e_book_get_contact (book, contact_id, &contact, NULL);

printf ("contact name == %s\n", e_contact_get_const (contact,


We still need a mainloop running somewhere, and (trusting glib's thread
safety when it comes to multiple mainloops running on the same context),
it's safe if you don't care on which thread your GSource callbacks are
executed (which ebook doesn't).

It doesn't seem to adversely affect evolution, fwiw.
