Bruce Evans b50641ef9c Fixed glitches (jumps) of about 1/HZ seconds for the i8254 timecounter. ... The old version only worked right when the time was read strictly more often than every 1/HZ seconds, but we only guarantee reading it every (1/HZ + epsilon) seconds. Part of rev.1.126-1.127 attempted to fix this but didn't succeed. Detect counter rollover using the heuristic from the old version of microtime() with additional complications for supporting calls from fast interrupt handlers. This works provided i8254 interrupts are not delayed by more than 1/(2*HZ) seconds. This needs more comments, and cleanups for the SMP case, and more testing of the SMP case before it is merged into RELENG_3. Tested by: jhay		1999-05-28 14:08:59 +00:00
