Apologies, my earlier email, item 2, pointed to emptyenv as the cause of
zombie processes on FreeBSD 12.2S, actually it is due to background.
Ah, then everything is working as intended and there's no anomaly.
background spawns a process as a direct child, so if the parent execs

2. Use of emptyenv results in a remnant "defunct" process
3. Should a bundle's contents file include the dependencies of its
contents file, for a down change to the
