This is another reason I've been delaying using fibers.  The correct approach is probably to go the distance by reserving a large block, committing only a portion, and commit the rest dynamically as needed.  The current fiber implementation does have a guard page in some cases, but doesn't go so far as to reserve/commit portions of a larger stack space.
