[wix-devs] BurnRunner implementation sometimes hangs on pipe.Write()

[Skylar Nam]

I hate to say this but for the actual run, we use different versions that
we are not in control of. Some are using 3.10, 3.11, many minor versions.
I can give you the versions that I've seen so far though. Some of them
include v3.10.2.2516 and v3.11.1.2318.
