And a question: rather than messing around with a constant which will
need to be increased again in a couple of years, can we solve this one
and for all? For example, permit root to set the system-wide
per-process max mlock size and depend upon initscripts to do this
appropriately.

Not sure I understand. Root and init scripts can already manage this
number - the goal of this patch is just to provide a saner default.

Well, why change the default?  Surely anyone who cares is altering it
at runtime anyway.  And if they are not, we should encourage them to do
so?
