4039 * A {@link PageDirectByteBuffer} is a custom variant of {@link DirectByteBuffer} for use
4140 * in VE for buffers that are multiples of the page size and have a lifetime that matches the VM.
4241 * They are allocated from virtual memory, whereas {@link DirectByteBuffer} uses malloc
4342 * memory and over-allocates in order to guarantee page alignment, resulting
44- * in 3 pages allocated when 1 is requested.

4645 * We invoke the private constructor provided for JNI_NewDirectByteBuffer using

4847 * so they cannot be reclaimed.
