// A BufferingOops closure tries to separate out the cost of finding roots
// from the cost of applying closures to them. It maintains an array of
// ref-containing locations. Until the array is full, applying the closure
// to an oop* merely records that location in the array. Since this
// closure app cost is small, an elapsed timer can approximately attribute
// all of this cost to the cost of finding the roots. When the array fills
// up, the wrapped closure is applied to all elements, keeping track of
// this elapsed time of this process, and leaving the array empty.
// The caller must be sure to call "done" to process any unprocessed
// buffered entries.
