I guess what you're doing is Insight is calling gdb_do_one_event repeatedly? And you want it to exit with a timeout so you can then run the Insight event loop? I don't really know the scenario here so I am just guessing. Anyway I don't understand why installing your own timer wouldn't work. It seems to me that if a timer is handled, gdb_do_one_event will return. Tom
