This is a bug in the C runtime that D uses, where pipes are not used  
correctly.  I'm working on getting Walter to fix it as it's needed for the  
new std.process as well.

Yes, but the main difference is, bearophile's method simply opens a file,  
which FILE * obviously supports no problem.  Your method creates a process  
with a pipe as the input.
