Hi Devs-

Does anyone know what our mingw64 g++ version for the nightly builds' 
support for C++11 is?  There are a few bug reports of odd locking 
behavior[1][2].  These seem to be when the user gets to the dynamic 
ratsnest update.

So, thinking that our use of atomic might be problematic, I've adjusted 
this a few times, finally going to std::async with std::futures 
promises.  This seems to have cleared the issue for [1] but made [2] 
worse.

Both std::async and std::future have been supported on Linux gcc since 
at least 4.7 but I've read in a few places [3][4] that it might not work 
in mingw64.  I can't seem to find a list of supported features anywhere. 
 Does anyone have a reference?
