I'm not sure. The block layer might e.g. legitimately buffer blocks

Not for the input file in fill mode, and not for the output file with
the new --synchronous option of ddrescue 1.8-pre2.
I didn't mean the block buffering from ddrescue, but the block layer of
the OS kernel.
When invoked with the --synchronous option, ddrescue follows every call
to writeblock with a call to fsync. So the kernel shouldn't be
clustering writes.
