[Backgroundrb-devel] Zombies?

[skaar]

ok, this was was lingering for a while as I suspected it was related to
another issue, but if you are running off trunk, the fix for this is in
as of:

  http://backgroundrb.devjavu.com/projects/backgroundrb/changeset/160

we shouldn't be that far off from 0.2.1 now.

>    jobs[key].shutdown? to see if the job is dead, it returns false,
>    indicating the the job isn't "shut down". So, I can't seem to have the
