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:
