```yes, pausing before execute would totally work!```
Current here is what the test does (_italics indicate what we're doing
under the covers_):
1. Init Statement
2. Set timeout on statement (_validating the timeout value_)
3. Calling `execute()` and fetching ResultSet instance (_starting the
clock_)
4. Fetching a row using ResultSet.next()
5. Pausing briefly
6. Repeat step 4 onwards (_enough pause to trigger timeout_)
I was intending to pause between step 3 and 4 as an additional step.
You believe that we are not exercising any tests for timeout within the
`execute()` call?
