It sure would be great if someone took this on.  Twisted would welcome 
better high-level tools that build on spawnProcess (apropos, Twisted 
would also welcome a better low-level tool to replace spawnProcess).

Considering the amount of maintenance Ampoule seems to have gotten over 
the last four years (~1 commit) I doubt you can count on someone else 
picking this up just because it would be great, though.
