This next value is the size, in kilobytes, of your largest cache.  ATLAS
will flush this much memory between timing calls, in order to ensure timings
are not inflated by cache preloading.  If you do not know the size of your
largest cache, a maximum value is fine.  The only drawback to making this
value large is that it requires more memory to do timings, and may slow down
the install process (if you have only a small amount of memory, it can also
invalidate the timings by causing the timers to swap).  While the default given
below should be a safe maximum for your system, it is possible that your actual
cache is smaller.  If you are certain that your largest cache is smaller than
the default given below, expedite the install by changing it.  Otherwise, just
hit enter to continue.
