it starts an EXPLAIN of a multi-table join and tries to KILL it. no sync points. depending on how fast the hareware is and optimizer development it might kill EXPLAIN at some random point in time (generally unrelated to the Bug#28598 it was supposed to test) or EXPLAIN might finish before the KILL and the test will fail.
