In the static allocation option, the rate of increase is the rate of new
ID-needing software ported to the tree minus - optimistically - the rate
of treecleaning similar software.  Optimistic because I am not sure how
much, or at what point, do we want to re-use treecleaned IDs.

In the dynamic case, we dont care about the global status and are really
bound by the max number of sysem IDs installed in a single system.
Local maximum is rather stable and in any case is a lot smaller than
global maximum.  Plus in this age of containers and namespaces, this
isnt really a problem even if it did grow over time, i.e. even if
unbounded, we have tools to manage it.
