That's a separate issue, i.e. a resource allocation
localization/globalization issue.  The main reason for these limits is
top put a cap on the amount of low kernel memory used on 32-bit systems
especially, which is somewhat inherently global.

Resource limit partitioning is a much bigger and orthogonal problem.
