Windows Builder Disabled

I have disabled the windows builder as it is consistently failing with the same error message.

From this log for example: https://phabricator.haskell.org/harbormaster/build/14430/

ghc.exe: getMBlocks: VirtualAlloc MEM_COMMIT failed: The paging file is too small for this operation to complete. 764ghc.exe: failed to create OS thread: The paging file is too small for this operation to complete. Do you have any ideas Ben/Tamar? I can't see any recent commits which would have caused this failure. Matt
