Really, I did mean that "m" is worse than "memory" (say, "in
general"), but it was choosen to use and it is enigmatic for me.
There was a discussion in the past about the advantages given by "m"
over just "memory". And as I understand, these advantages are really
nothing. But the dummy code size they added to, say, glibc-2.3.2 is
6Kb.

Semantics? Or may be implementation? It seems that all ok with the
semantics...
