Re: Gio FTP transfers stops after 25 seconds

[Mathieu Comandon <strycore gmail com>]

The method isn't available because it's not introspectable. copy_async
requires multiple callbacks and user data argument, which is not
implemented yet in gobject-introspection. There's a bug report on Launchpad
about this:
https://bugs.launchpad.net/ubuntu/+source/gobject-introspection/+bug/1033196
and
it's been triaged by Martin Pitt himself so I'm quite sure that this will
be solved in the near future.

Meanwhile, I'm using the io_scheduler_push_job trick and it seems to work
fine except for FTP. I'm even starting to use io_scheduler_push_job to put
in background things that are not at all related to Gio (like
subprocess.Popen() calls). I'm still not sure that is the correct way of
doing things but until I find a better one, that will do.
