All true, and expressed with precision.

However, naive developers sometimes infer very shaky
conclusions from these propositions.  select is quite
efficient--more than many people realize--and
generally a safe recommendation.  What can really go
wrong in this area is that the misguided think that
they should avoid select, and so start polling in a
multithreaded arrangement (!).  I've never seen *that*
come to a happy end.
