@param ctx The execution context to use.
@param size The payload's size, in bytes.
@discussion Use this function to notify the garbage collector that a GC object
owns a large non-GC memory region. Calling this function will encourage the
garbage collector to collect soon, hoping to reclaim that large non-GC memory
region.
