I tested this patchset for ~22 hours without any issues using my own leap second
test code, John's previous leaptest.c and this new leap-a-day test with and
without the -s option.

In all x86 systems' cases (both AMD and Intel, large cpu count[1] and small cpu
count) I also ran Firefox in the background and monitored it using top and
occasionally breaking in to check the status of the futexes.  I haven't seen
anything wrong with any of the systems.

John, my apologies for not getting to exactly 24 hours.  I've usurped these
systems long enough and other people need them :/.  I'm going to continue to run
two systems (one AMD and one Intel) for a longer stretch but I don't anticipate
any issues at this point.

So ...

For the entire patchset.
