How about this, when Iothread's GMainContext is NULL, use io_poll, or else use
g_main_context_* poll the fds ?
Iothread's GMainContext is NULL by default,so use aio_poll in iothread_run
function.
In addition we can create a new GMainContext in chardev,use g_main_context_* in
iothread_run.
Maybe this doesn't affect performance ?
Thanks

I don't knoe. Maintain a flag and only do these slow stuff after at least one
GSource has been moved around?
