L{twisted.internet.reactor.seconds} should return something
like a number.
1. This test specifically does not assert any relation to the
"system time" as returned by L{time.time} or
L{twisted.python.runtime.seconds}, because at some point we
may find a better option for scheduling calls than
wallclock-time.
2. This test *also* does not assert anything about the type of
the result, because operations may not return ints or
floats: For example, datetime-datetime == timedelta(0).

DummyProducera�
Very uninteresting producer implementation used by tests to ensure the
right methods are called by the consumer with which it is registered.
@type events: C{list} of C{str}
@ivar events: The producer/consumer related events which have happened to
this producer. Strings in this list may be C{'resume'}, C{'stop'}, or
C{'pause'}. Elements are added as they occur.

A descriptor whose data buffer gets filled very fast.
Useful for testing FileDescriptor's IConsumer interface, since
the data buffer fills as soon as at least four characters are
written to it, and gets emptied in a single doWrite() cycle.

Similar to L{DummyProducer}, but with a resumeProducing method which calls
back into an L{IConsumer} method of the consumer against which it is
registered.
@ivar consumer: The consumer with which this producer has been or will
be registered.

C{resumeProducing}.

C{resumeProducing}.
