i just never used such functionality and asked community to ensure
that i don't selected anything wrong. sometime ago i've reimplemented the
feature that is in standard lib (unechoed input) so i just tried to
use community's wisdom this time :)

so,

do (stdin,stdout,stderr,ph) <- runInteractiveCommand "script param"
   waitForProcess ph

when i should read stdout? before or after waitForProcess?
