      wiredtiger-test-format-stress-ppc failed due to EBUSY during verify.

      I tried to reproduce on Linux, but was unable to after 100 runs.

      Error looks like this:

      t: FAILED: check_copy/49: session->verify(session, g.uri, NULL): RUNDIR/BACKUP: file:wt: Device or resource busy
      + cleanup
      + status=1
      + '[' -f RUNDIR/CONFIG ']'
      + cat RUNDIR/CONFIG
      

      Config is:
