Antirez has a new memory optimization branch - antirez/redis@unstable...memopt
Smaller strings (less than 32 bytes) are inlined. This gets rid of an extra pointer, and so saves some memory (not a whole lot). Not a big deal, but something that we should account never the less.
This should be fixed only after the optimization branch reaches unstable/master branch.
