It would be important for the new option to be backportable 
independently. Therefore mixing it with -numa is not an option.

Also due to backportability supporting a new style of command line
for -mem-path is problematic (management must be changed accordingly).

Can the new option format for memory be created incrementally on 
top of -mem-path-force? (agree its a good thing, it avoids proliferation
of new options).
