Did you use gcc on Unix?  If so, you should notice that in most cases it 
doesn't use pipes by default there either.  The reason is that with 
pipes, it doesn't run faster, but imposes a huge CPU load on the system 
(because pipes are imlpemented as memory moves).  Last time I looked, gcc 
docs doesn't recommend using the -pipe option due to this.

OTOH, if you have a sufficiently large disk cache set up to deferred-write
operation, you already have the same gains as pipes would give you.
