I see no reason why we need two limits for memblock.
And if we really require two limits then please use a function
to set it.
All other setup/etc. towoards memblock is via function,
and starting to introduce magic variables is confusing.

Also new stuff in memblock shal have a nice comment
describing the usage. that we in the past has failed to
do so is no excuse.
