No trouble, it just won't get a proper response...

Try unremming the wxPrintf statement in wxLuaState_newthread_handler
in modules/wxlua/src/wxlstate.cpp and see if that gets run when the
coroutine is created. We had to make changes for running wxLua as a
lua module for require, maybe it's broken now.

ps. could you send a little coroutine code to show the problem, we
could add it as a sample in wxLua to help verify that they still work.
I seem to have lost my little sample.
