Attached patch shows my current progress with the isolation test.

I also attach diff output of the FreeBSD failures. Notice that the
line "backwards_scan_session: NOTICE: notice triggered for injection
point lock-and-validate-new-lastcurrblkno" is completely absent from
the test output. This absence indicates that the desired test coverage
is totally missing on FreeBSD -- so the test is completely broken on
FreeBSD.

I ran "meson test --suite setup --suite nbtree -q --print-errorlogs"
in a loop 500 times on my Debian workstation without seeing any
failures. Seems stable there. Whereas the FreeBSD target hasn't even
passed once out of more than a dozen attempts. Seems to be reliably
broken on FreeBSD.

Thanks
