To make it clear: push is when the nodes determine what templates will
be selected for processing -- not when just the order of processing is
not guaranteed.

When we know what template will be selected for processing, then we
have pull processing.

Truly great madness cannot be achieved without significant intelligence.
To invent, you need a good imagination and a pile of junk
Never fight an inanimate object
You've achieved success in your field when you don't know whether what
you're doing is work or play
I enjoy the massacre of ads. This sentence will slaughter ads without
a messy bloodbath.
