It doesn't *look* to be arch-specific, but I haven't tested others. It
may just be the way my test works.

Starting at:
  244a56681 file-posix: Add image locking to perm operations

My test case (attached to this bug) began to fail with:

error: Failed to start domain 7936-0
error: internal error: process exited while connecting to monitor:
