Hitting a gnat with a hammer.

Something that may make more sense is a PopenPipe that changes the
default for stdin/out/err to be distinct pipes rather than inherited
from the parent (but still able to be set explicitly). It is certainly
annoying that creating a fully piped subprocess is so verbose.
