Declared in `<bdlma_heapbypassallocator.h>`

Create an empty allocator object. Optionally specify `replenishHint` as the minimum number of bytes to allocate at a time when the allocator's memory needs to grow. In a multi‐threaded scenario, the programmer should ensure that `replenishHint` is large enough so that multiple threads will rarely need to replenish at the same time in order to minimize contention.
