seems to be silently broken in 10.2 or why is there a fat temp-file as well as the progress display from previous versions don't work in 10.1/10.2 in a useable way (a pseudo progress for small tables is nice but when you see no output at all when 'optimize table' is running on a table with 10 GB it's broken)

"innodb-defragment = 1" is set
