stack setup ghcjs fails

[ndmitchell]

Running stack setup --compiler ghcjs-0.1.0.20150924_ghc-7.10.2 with Stack Version 0.1.9.0, Git revision 1482c5c52a59c7a6f607570c65be5dc3f0387bcf i386 on Windows it proceeds for a while (maybe 30 mins?) then gets stuck. The console says:

There is also a node process with the command line:

"C:\Program Files\nodejs\node.exe" "C:\Users\ndmit_000\AppData\Roaming\ghcjs\i386-mingw32-0.1.0.20150924-7.10.2\ghcjs\thrunner.js"

Neither of the processes are taking any CPU or have any visible signs of further progress after waiting an hour.

Perhaps it's related to node version? See #1629 / #1496

I think one way or another this is an upstream issue. Feel free to re-open if you suspect otherwise.
