memory profiling

[Havoc Pennington]

Hi,

How hard would it be to assign sub-application-granularity "blame" for
all the memory used by a full desktop (GNOME+Evolution+Mozilla+OO.org)?

Something like:

   5M   sum of per-app icon theme caching
   5M   sum of per-app base gtk_init() overhead
   10M  sum of per-email data in Evolution 
   7M   base evo overhead with no mail loaded
   30M  sum of all executable pages (libraries and binaries)
   ...

i.e. try to get an idea of where focused optimization could have the
most impact on the desktop overall - what percentage of TOTAL memory
usage for the whole desktop can be blamed on each optimizable item, with
sufficient granularity to be useful.
