[Mark Harmer <drivehappy@xxxxxxxxx>]

I've attached a proposed patch.

One thing of note is that this actually keeps the Glib::MainLoop, after
reading more into it, it appears that a recursive call to running a main
loop is supported.

The actual problem is that this was reusing the default MainContext
which had all of the original input sources. This patch builds a new
MainContext for the new MainLoop, and with each file_listener::init
connects the stdout and stderr it to this new context.

This causes the expected blocking UI behavior until the script has
completed saving since the new context shouldn't have any other sources.
Unfortunately this does cause the UI to appear to  be hung until the
script completes the save, but given Johan's statement it sounds like it
might be a reasonable fix until multithreading can be added.
