Chris Nauroth resolved MAPREDUCE-4872.
--------------------------------------
    Resolution: Won't Fix

I'm going to close this as won't fix.  In practice, this doesn't really cause anything to break, because even on Windows, the container launch script explicitly sets a value for the {{PWD}} environment variable.  Even though this environment variable name is more of a Unix-like convention, there isn't a compelling reason to make a change.

> {{MapReduceChildJVM#getVMCommand}} sets java.io.tmpdir by using environment variable PWD as the root of the path.  On Windows, %PWD% likely will not be defined.  Instead, we need to use %CD%.  Any part of the codebase that uses {{Environment#PWD}} is likely to be impacted by this.
