- Second scenario checked:
Ensure via wait routines that the commit comes after the
processing of the statement which should get finally
the ER_LOCK_WAIT_TIMEOUT
--> This should prevent the current bug.
- First scenario checked:
Ensure via wait routines that the statement is already waiting
for getting the lock before the commit is given.
--> No effect on the current bug, but ensure that the right
scenario is reached.
- Take care that disconnects are finished before the test ends.
--> Reduce the potential to harm succeeding tests.
- "Mangle" the printout of the current default innodb_lock_wait_timeout value
--> No need to adjust the test in case the default gets changed in future.
