I think I don't understand the difference between (send ...) and (send-off ...), but that may be where the difference in behavior between our otherwise very similar code arises. > > > Why can the program terminate before all the output from the sub- > > > process has been passed through? > > > > As long as the sub-process produces no more output than the > > operating system's pipe buffering limit, it can complete without > > blocking. > > My question was not precise enough.

Well, your code may not work at the moment, but the approach is sound, as my code points out (it does work). > > ... > > Thanks for sharing this.
