Given the hardware braindamage it is relatively sane.  As always, it
would be much better to fix the problem and not add workarounds, but we
seem to lack the gods favor this time around.

Can't anyone explain to the SATA folks that a discard is much closer to
a write than to a secure erase or some other rare and slow command?
