Sure, please do.  I'm not overly fond of the name I gave it,
popen is definitely better.

Maybe it would be a good thing to add a remark to the
documentation of runProcess, to mention popen.
Also, I think runProcess can be made to work with pipes,
but it requires some cheating with unsafePerformIO to
force the child to close the file descriptors...
Fork is the tool of the demon !
