Good point. Verifying that the new überblock is readable isn’t actually
sufficient, since it might become unreadable in the future. You’d need to wait
for several transaction groups, until the block was unreachable by the oldest
remaining überblock, to be safe in this sense.
On the other hand, one could make an argument that since the file had been
deleted, it would be reasonable for its data to be unreadable after a crash.
The data would be unreadable because the ZIL would be used and the file
would be marked as deleted. The bleaching transaction would be in the
ZIL as well.
