                     33: **
                     34: **     Please note that it is VERY important that you reset your
                     35: **     warp speed after the automatic override is called.  The new
                     36: **     warp factor does not stay in effect for just this routine.

                     38: **     This routine will never try to send you more than sqrt(2)
                     39: **     quadrants, since that is all that is needed.
