  * Catch exit exceptions as well as IO exceptions after running programs
  We need to catch IO exceptions for things like "couldn't find the program",
  but we also need to catch exit exceptions as Cabal uses them to signal
  what the program returned.

    M ./Distribution/Simple/Configure.hs -2 +3
    M ./Distribution/Simple/GHC.hs -1 +2
    M ./Distribution/Simple/Program.hs -2 +3
