Delta-composer && (undefined but required) stream behaviour

While writing new streams which I want to use to feed the delta
composer, I noticed the delta composer expects streams to support
reads after partial results have been returned. Ofcourse, a read like
that should return a zero-length block, but nowhere in the stream docs
is this requirement documented.

Is it a bug in the window composer, or in the stream documentation?

(I'm tempted to say it's a bug in the window composer, but that it's
desirable to have streams support the behaviour even if we fix the
window composer...)

bye,

Erik.
