No, I think you got that right ... the runtime process size and  
efficiency of heap allocation can vary a lot depending on the  
libraries.  But the pure storage in Emacs doesn't get allocated that  
way; it comes out of a statically allocated array named pure[] in  
alloc.c, which has its own allocation routines (pure_alloc and friends).
