Of course not, even ext3 has delayed allocation (even if 5 sec vs. 2 min
makes the disaster window a bit smaller).

The real problem seems to be that ext4 re-orders the rename (which it
does almost instantly) before the write (which waits for 2-15 minutes or
so).

There are other modern filesystems that take care such reordering
doesn't happen...
