Just a clarification: USE_LSB_TAG is not an really optimization, or at
least I don't think anyone has tried to measure its performance. It is
meant to let Emacs use all the available virtual memory rather than be
limited to 128MB (IIRC) of memory on 32bit systems (not to be confused
with the limit on maximum buffer size, which is determined by the
largest fixnum, i.e. 512MB on 32bit systems on the trunk).
