bitkeeper revision 1.1159.1.295 (4180ee31v7apKAXQ_iCd672ndA6I0Q)
New TLB-flush logic. By basing NEED_FLUSH() on the current time, as
well as the CPU and page timestamps, I was able to get rid of the
tedious epoch logic. We now only need special-case logic when the
32-bit clock wraps. In debug build I deliberately restrict the clock to
10 bits, so that the wrap logic gets exercised.
