Thank you.  A couple of concluding remarks ...

Would it be worthwhile to put that entire thing in #ifdef DEBUG ?
Perhaps not, given that the bgstatus_list is unlikely to have many
nodes.

Irrelevant to the patch, but on the original issue, I keep looking at
this and wondering how we got an exit code of 19 rather than 19+128
which would have immediately pointed to SIGCONT.  Is this a difference
in the way MacOS defines WEXITSTATUS(), or what?
