* reading from a socket that gave some data we weren't looking for and
then closed.
* read from a socket that stays open and never sends data.
* reading from a socket that sends data but not the data we're looking

Fixes#2051
Context: I recently discovered that when setting a fact, key=value pairs and complex arguments differ in how the fact is stored. For example, when attempting to use complex arguments using key=values, the result can be stored as a unicode string as opposed to an object/list/etc.
I'm hoping the above example update will better demonstrate to and instruct people to use complex arguments instead of key=value pairs in certain situations.
