 On b5, the test went from failing reliably to failing randomly:

 So far, I have reproduced the failures on two different testbeds where
 the system under test runs under qemu hosted on NetBSD, but have not
 been able to reproduce it on real hardware, nor on qemu hosted on
 Linux.  This suggests the issue may be yet another manifestation of
 PR kern/43997.
