> Sine the SpillableMemoryManager subscribed the memory notifications, and hold a weak
reference of all the spillable, if there's too many weak reference and the memory exceeds
the threshold, the current code will not clear the spillable weak references.
> the details is illustrated in the attached screenshot of a MemoryAnalyzer.
> So we need to clear the spillables when the memory notifications is received.
