In fact, my windows changes are merged into Lars' branch  
(https://github.com/kyllingstad/phobos/tree/new-std-process)

*BUT*  (and this is a big but), dmc's runtime incorrectly handles pipes  
with C's stdio (i.e. FILE *).  Since everything in D right now is FILE *  
based, it means you can't use pipes at all.

However, I have submitted a patch for DMC's runtime to Walter.  Hopefully  
it will be approved in the near future, and then we can work on merging  
the new std.process into phobos.
