  Modified files:
    bin/sh               jobs.c jobs.h trap.c 
  Log:
  If traps are set, they are now executed even when a signal-blocking
  foreground child is running. Formerly, traps were exceuted after the
  next child exit.
  
  The enables the user to put a breaking wrapper around a blocking
  application:
    (trap 'echo trap ; exit 1' 2; ./pestyblocker; echo -n)
  
  The "echo -n" after the child call is needed to prevent sh from
  optimizing the trap-executing shell away. I'm working on this.
