  Great, I remember why I chose to use a macro.
  There's no good paradigm for passing the variadic arguments of printf
  through another function.

  I can use a paradigm wherein you just call the timestamper immediately
  before printf()-ing your message, but like,
  I dunno.

  Let's see whether I can split the log(X) macro into this and a
  function in log.h that supplies the time
