[pkg-fgfs-crew] Bug#750939: flightgear: Occasional deadlock when processing key input

[Rebecca N. Palmer]

Control: tags -1 upstream patch

I have now tried this patch, and while I can't tell if it fixes the 
problem (as I never had it), it at least doesn't appear to break 
anything else.

No comment from upstream on this particular patch, only a general 
concern that other multithreading bugs might exist (very possible, but 
not a reason not to fix this one).
