The current status is that the POSIX version works, and has done so for
a while.  Its incorporation in Phobos, and development of the Windows
implementation, has been blocked by a DMD bug which is now fixed in SVN.

So I guess the next steps will be
  1. Wait for next DMD release, which will contain aforementioned fix.
  2. Finish up Windows version.
  3. Code review and hopefully acceptance in time for following release.
[ 4. Deprecation and subsequent death of File.popen(). ;) ]
