  - Avoid race while synchronizing components. It is very hard to bump into,
    but it is possible:
    1. Read data from good component for synchronization.
    2. Write data to the same area.
    3. Write synchronization data, which are now stale.
  - Decrease kern.geom.mirror.timeout to 4, so it is smaller than
    vfs.root.mountdelay by default.
  - Don't skip providers with 0 sectorsize.
