Yes, I'm testing power-fail tolerance!  The RFS is mounted in sync mode
so unless I'm missing something the sync should have occurred before the
command prompt reappears, right?

Ideally, yes and "sync" before power-down works but that's not what
these tests are checking.  With the RFS not in sync mode, it works;
"sync" command with sync mount currently untested.
