threadName
- the name of the thread (to allow identifying the thread)check
- the BackgroundCheck to periodically invoke with check()callback
- the Runnable to invoke upon a successful check()timeoutMillis
- a timeout at which point the BackgroundCheck is
terminated and no callback is invoked. Note that this happens unnoticed
at the moment, ie there is no feedback about whether a background
check was successfully termianted (ie callback was invoked) or
whether the timeout has hit (that's left as a TODO if needed).protected void triggerBackgroundCheck()
