Problem: show slave status may return different Slave_IO_Running values running some tests.
Fix: wait for a certain slave state if needed to get tests more predictable.
- Add test case that shows how slave server hangs in "STOP SLAVE"
when run on MySQL version 5.0.33 compiled with OpenSSL.
Works fine with latest version of MySQL since that problem
has been fixed by patch for bug#24148. The fix has been noted in
the changelog for MySQL 5.0.36
