Whether it's for a static or dynamic allocation doesn't matter: the
places where some arbitrary number is used, it's usually 100.

Actually 32 is no better than 42 or 100.  The important part is that
people shouldn't feel compelled to change 100 to 96 (or 32 to 28) when
they reduce a size by 4.

EXTRA_SPACE sounds fine,
