Okay, I think I'm seeing a pattern here.
It seems I can successfully change the block size if there is no
tape inserted. (Or after an "mt offline", which presumably amounts to
the same thing even if the tape is still physically in the drive.)

Changing the block size after a tape has been inserted but not yet
read from works sometimes. No recognizable pattern yet. Changing
the block size after the tape has been read from fails reliably.
