POSIX has the following to say with respect to the 'jobs' utility:
When jobs reports the termination status of a job, the shell shall remove
its process ID from the list of those known in the current shell

With Bash, this is not the case for 'jobs' called from within a SIGCHLD
handler.
I'll take a look. Until last November, the bash `jobs' builtin didn't
remove jobs from the jobs list at all.
