This won't work reliably. All file operations run in threads, so calls
to e.g. thuner_application_unlink_files() will return immediately and
if you reload the standard view directly after that, not all files may
be gone yet.

I tried a few similar things but reloading the current folder all the
time will make Thunar very busy and will slow down your machine.

ThunarVFS used a timeout for forced change events to speed things up
but unlike GIO it had a singleton file monitor which made reacting on
these things easier.
