I am experimenting with using manual control of the Glib event loop using the pending and iteration methods on the default MainContext within each unit- threaded test. The alternative of running a GTK application and then putting the tests in as an asynchronous sequence only works with Rust and Python since D has no coroutines of any sort. Of course now there is jin.go which is a synchronous multi-tasking approach with channels rather than an asynchronous approach available in D. -- Russel. =========================================== Dr Russel Winder t: +44 20 7585 2200 41 Buckmaster Road m: +44 7770 465 077 London SW11 1EN, UK w: www.russel.org.uk
