There is a completely revamped version of std.process.  It is being held  
up right now because DMD on windows depends on DMC for it's C runtime, and  
DMC has issues supporting pipes.  I have recently opened a pull request  
for Walter to merge, I'm going to ping him about it right after 2.057 is  
released.

For more info, see the docs Lars posted here:

Once the DMC issue is fixed, you should see this improvement getting much  
more attention.  It's very low hanging fruit.
