static void disposeStrike(final FontStrikeDisposer disposer) {

// because they may be accessed on that thread at the time of the
// disposal (for example, when the accel. cache is invalidated)
// Whilst this is a bit heavyweight, in most applications
// strike disposal is a relatively infrequent operation, so it
// doesn't matter. But in some tests that use vast numbers
// of strikes, the switching back and forth is measurable.
// So the "pollRemove" call is added to batch up the work.
// If we are polling we know we've already been called back
// and can directly dispose the record.
// Also worrisome is the necessity of getting a GC here.
