Bash Version: 3.1
Patch Level: 17
Release Status: release

Description:
        When process substitution is used, BASH doesn't make setpgrp() call
        so, substituted process run in the same process group
Repeat-By:
        exec 3< <( kill -KILL 0 )
Fix:
       I think, that BASH SHOULD MAKE new process group in same manner
       as it does, when job control is enabled, and "command &" used.
       
       My real script runs program, that call kill(0, SIGKILL).
       and my script terminates.
