Some tests show that when the serial regression tests are run in a
freshly initdb'd installation, HEAD assigns OID 29270 to "bmscantest"
in the bitmapops test.  So that's been dropped some time before the
failure occurs; which means that this isn't a narrow-window race
condition; which raises the question of why we're not seeing it on more
machines.  I notice now that kudu and dragonfly are actually the same
machine ... could this be an OS-specific problem?  Kris, has there been
any system-software change on that machine recently?
