312 - USE_LSB_TAG means that we can assume the least 3 bits of pointers are

314 restricting our addressing space.

317 restricting our possible address range. Currently USE_LSB_TAG is not

319 technical (or political ;-) problem: nobody wrote the code to do it yet.

1787 Typing C-g does not directly cause a quit; it only sets Vquit_flag.
1788 So the program needs to do QUIT at times when it is safe to quit.
1789 Every loop that might run for a long time or might not exit
1790 ought to do QUIT at least once, at a safe place.
1791 Unless that is impossible, of course.
1792 But it is very desirable to avoid creating loops where QUIT is impossible.
1794 Exception: if you set immediate_quit to nonzero,
1795 then the handler that responds to the C-g does the quit itself.
1796 This is a good thing to do around a loop that has no side effects
1797 and (in particular) cannot call arbitrary Lisp code. */
