Description

Printing is super expensive; I just ran a property where each test case takes very little time. 200 000 tests took 14 seconds, but 200 000 tests with chatty = False took 4 seconds. Such a huge penalty for just printing!

chatty = False is not always ideal, as I am interested in the current progress of my property. There should be some half-way option where I can ask for output, but less. I am just not interested in unperceived updates :) I have a patch ready to go for this, but I document this here so that this is not forgotten.
