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.
