No, those are just hints for allocation of default-sized blocks. They
don't constrain allocation of blocks that have to be a particular size
to accommodate a large chunk. The reason for having them is just to
allow a caller who expects that a particular context won't contain much
data to prevent a lot of wasted space from being allocated for big
default-sized blocks.
