Hi Stefan,

IOThread does not run a GMainContext, I think we can create a new GMainContext

in the IOThread and attach IOThread's AioContext to the GMainContext , 

finally use g_main_loop_run to replace aio_poll  in the iothread_run function.

After that IOThread runs the GMainContext event loop,chardev and IOThread can 
work together.

How about it? If feasible, I will try to submit a patch.




Thanks

A follow-up:

I just noticed that io/ supports AioContext.

This means a different approach is to add AioContext support to the
chardev API so that either GMainContext or AioContext can be used.

Again, I'm not sure how feasible this is.
