Bug#21781 Replication slave io thread hangs

Browse Source 
- 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
