Fixing a SpellChecker leak in Android M
/**
* Every editable TextView has an Editor instance which has a SpellChecker instance. SpellChecker
* is in charge of displaying the little squiggle spans that show typos. SpellChecker starts a
* SpellCheckerSession as needed and then closes it when the TextView is detached from the window.
* A SpellCheckerSession is in charge of communicating with the spell checker service (which lives
* in another process) through TextServicesManager.
*
* The SpellChecker sends the TextView content to the spell checker service every 400ms, ie every
* time the service calls back with a result the SpellChecker schedules another check for 400ms
* later.
