That's a welcome improvement, but you may want to also look at
06333955bf3d ("tests/kms_cursor_crc: start crc only once per test")
for some extra inspiration for future work on this.
It should be possible to initiate pipe crc to be initalized only once
per each tested pipe in run_tests_on_pipe() - igt_pipe_crc_new() can be
costly on some real panels.
Anyway,
