BASH PATCH REPORT
=================
Bash-Release: 3.2
Patch-ID: bash32-018
Bug-Reported-by: osicka@post.cz
Bug-Reference-ID: <228.177-19682-1132061412-1179356692@post.cz>
Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-bash/2007-05/msg00061.html
Bug-Description:
In certain cases, bash can lose the saved status of a background job, though
it should still be reported by `wait'. Bash can also loop infinitely after
creating and waiting for 4096 jobs.
Patch:
