Thank you for the patch.
But what about this existing interface (only recently documented)?
Note that sending a `SIGUSR1' signal to a running `dd' process makes
it print to standard error the number of records read and written so
far, then to resume copying. In the example below, `dd' is run in the
background to copy 10 million blocks. The `kill' command makes it
output the first pair of intermediate record counts, and when `dd'
completes, it outputs the final pair.
$ dd if=/dev/zero of=/dev/null count 10M & pid=$!
$ kill -USR1 $pid; sleep 99
5403604+0 records in
5403604+0 records out
10485760+0 records in
10485760+0 records out
