Bug#760847: gvfs: File copy fails with "Another operation in progress" still present in 1.22.2-1

[Marcin Szewczyk]

I would like to propose a patch (attached). It's probably too primitive
and requires a rewrite to become event-driven instead of a polling
mechanism. But for me it works and I've found another polling part in
the code that was already there so maybe the quality loss isn't that big
after all ;)

I kindly ask for a review/opinions and feedback.
