- *         allocate space for XXXROUNDUP(current_size + 1) total children

- *
- * Since a node starts out empty, we must have
- *
- *     XXXROUNDUP(0) < XXXROUNDUP(1)
- *
- * so that we allocate space for the first child.  One-child nodes are very
- * common (presumably that would change if we used a more abstract form
- * of syntax tree), so to avoid wasting memory it's desirable that
- * XXXROUNDUP(1) == 1.  That in turn forces XXXROUNDUP(0) == 0.
- *
- * Else for 2 <= n <= 128, we round up to the closest multiple of 4.  Why 4?
- * Rounding up to a multiple of an exact power of 2 is very efficient, and
- * most nodes with more than one child have <= 4 kids.
- *
- * Else we call fancy_roundup() to grow proportionately to n.  We've got an
- * extreme case then (like test_longexp.py), and on many platforms doing
- * anything less than proportional growth leads to exorbitant runtime
- * (e.g., MacPython), or extreme fragmentation of user address space (e.g.,
- * Win98).
- *
- * In a run of compileall across the 2.3a0 Lib directory, Andrew MacIntyre
- * reported that, with this scheme, 89% of PyObject_REALLOC calls in
- * PyNode_AddChild passed 1 for the size, and 9% passed 4.  So this usually
- * wastes very little memory, but is very effective at sidestepping
- * platform-realloc disasters on vulnerable platforms.
- *
- * Note that this would be straightforward if a node stored its current
- * capacity.  The code is tricky to avoid that.
