The order of calls scheduled by L{task.Clock.callLater} is honored when
adding a new call via calling L{task.Clock.callLater} again.
For example, if L{task.Clock.callLater} is invoked with a callable "A"
and a time t0, and then the L{IDelayedCall} which results from that is
C{reset} to a later time t2 which is greater than t0, and I{then}
L{task.Clock.callLater} is invoked again with a callable "B", and time
t1 which is less than t2 but greater than t0, "B" will be invoked before
"A".

When L{LoopingCall} schedules itself to run again, if more than the
specified interval has passed, it should schedule the next call for the
next interval which is still in the future. If it was created
using L{LoopingCall.withCount}, a positional argument will be
inserted at the beginning of the argument list, indicating the number
of calls that should have been made.

L{LoopingCall.withCount} counts only calls that were expected to be
made. So, if more than one, but less than two intervals pass between
invocations, it won't increase the count above 1. For example, a
L{LoopingCall} with interval T expects to be invoked at T, 2T, 3T, etc.
However, the reactor takes some time to get around to calling it, so in
practice it will be called at T+something, 2T+something, 3T+something;
and due to other things going on in the reactor, "something" is
variable. It won't increase the count unless "something" is greater
than T. So if the L{LoopingCall} is invoked at T, 2.75T, and 3T,
the count has not increased, even though the distance between
invocation 1 and invocation 2 is 1.75T.

L{task.LoopingCall.withCount} should never invoke its callable with a
zero. Specifically, if a L{task.LoopingCall} created with C{withCount}
has its L{start <task.LoopingCall.start>} method invoked with a
floating-point number which introduces decimal inaccuracy when
multiplied or divided, such as "0.1", L{task.LoopingCall} will never
invoke its callable with 0. Also, the sum of all the values passed to
its callable as the "count" will be an integer, the number of intervals
that have elapsed.
This is a regression test for a particularly tricky case to implement.
