+1 from me, sounds easier to grasp, and looks like it would be
everything Oliver needs, too. Oliver?
setQueryTimeout() could by default only set "soft" timeout
(hardTimeoutMargin set to -1)
If hardTimeoutMargin is set to >= 0 you will get hard timeouts at
setQueryTimeout + margin. Margin can be 0 of course.
If you want to have soft/hard timeout for all queries, you set one or
both parameters.
Any use cases not working with just these two parameters?
