I presume this is due to the unsolved issue with GC: once
gc-cons-threshold is set to a large value, it effectively disables GC
for the rest of the session, even if after that gc-cons-threshold is
reset back.  If some of your customizations do something like that,
try invoking GC manually, via "M-x garbage-collect RET", after
gc-cons-threshold is set back to its nominal value, and see if the
problem with memory consumption goes away.
