Patch is in CVS.

Not 100% sure about the correct return code, if the lazy allocation
fails. Can you check that?

Matsunaga, I guess that the extra memory you now have on your machine
has more impact on performance than statical allocation would have.
Translate the saved memory into a monetary unit and you even have a
lart that works for managers.


You can't tell where a program is going to spend its time. Bottlenecks
occur in surprising places, so don't try to second guess and put in a
speed hack until you've proven that's where the bottleneck is.
