This is why I have the GLib source on Koders as a bookmark, some code
is good and some is very slow.  I must have mixed up the queue and
trash stack as the former keeps a count of the length.  I added a
!g_trash_stack_is_empty() call instead which makes the test a bit more
apparent.  Both the transmit and receive windows are affected.
