which is waiting on a third L{Deferred}, the middle L{Deferred}'s
callbacks are executed after the third L{Deferred} fires and before the

Let C{a} and C{b} be two L{Deferred}s.
If C{a} has no result and is returned from a callback on C{b} then when
C{a} fails, C{b}'s result becomes the L{Failure} that was C{a}'s result,
the result of C{a} becomes L{None} so that no unhandled error is logged

A fires.

L{Deferred}s can have callbacks that themselves return L{Deferred}s.
These L{Deferred}s can have other callbacks added before they are
returned, which subtly changes the callback chain. When these "inner"
L{Deferred}s fire (even asynchronously), the outer callback chain
continues.

Any recorded chaining is cleared once the chaining is resolved, since
it no longer exists.
In other words, if one L{Deferred} is recorded as depending on the

dependency is resolved and we no longer benefit from recording it.

Given three Deferreds, one chained to the next chained to the next,
callbacks on the middle Deferred which are added after the chain is
created are called once the last Deferred fires.
This is more of a regression-style test. It doesn't exercise any
particular code path through the current implementation of Deferred, but
it does exercise a broken codepath through one of the variations of the
implementation proposed as a resolution to ticket #411.
