Thread used to implement query timeouts...Eventually we could be more efficient and have one thread with timers, but this is a straightforward and simple way to implement a feature that isn't used all that often.

public boolean cancel()

Overrides java.util.TimerTask.cancel.

Implements com.mysql.cj.CancelQueryTask.cancel.

Doc from java.util.TimerTask.cancel.

Cancels this timer task. If the task has been scheduled for one-time execution and has not yet run, or has not yet been scheduled, it will never run. If the task has been scheduled for repeated execution, it will never run again. (If the task is running when this call occurs, the task will run to completion, but will never run again.)

Note that calling this method from within the run method of a repeating timer task absolutely guarantees that the timer task will not run again.

This method may be called repeatedly; the second and subsequent calls have no effect.

Returns:boolean

true if this task is scheduled for one-time execution and has not yet run, or this task is scheduled for repeated execution. Returns false if the task was scheduled for one-time execution and has already run, or if the task was never scheduled, or if the task was already cancelled. (Loosely speaking, this method returns true if it prevents one or more scheduled executions from taking place.)
