Both these kinds of HANDLE work transparently with ReadFile/WriteFile API
functions so should be fine with the underlying OCaml calls (OCaml's file
I/O is based on the C I/O routines which won't be using
ReadConsole/WriteConsole) - what scenario are you referring to where the
difference between a console handle and a pipe would be a problem?
