As an additional note here, my preference would also be for gdb to be used,
if only because it is more reliable and dependable.

Currently we have special code in the CI tooling to ensure that stray lldb
processes left behind by unit tests on our FreeBSD CI workers are all
killed off.
Otherwise they sit there eating up an entire CPU core at 100% utilisation
until an admin logs in and kills them off.
