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...
