Just tested running the full test suite on my laptop (release build):
(cd mysql-test && time ./mtr --mem --parallel=3 --force) -> 18:16.60elapsed
(cd mysql-test && time ./mtr --mem --parallel=3 --force --mysqld=--loose-innodb-fast-shutdown=2) -> 11:14.47elapsed
So that's 38% faster ... so fixing this does seem rather worth-while.
