Comment(by njs):

 About the name: my original version actually was called logdet(), but I
 worry that the expectation is that logdet() is -- modulo numerical issues
 -- the same as log(det()). But this API doesn't act like that -- it
 returns a 2-tuple, not a scalar!

 About the other commentary: I'm afraid I'm totally missing something; I
 don't know what you guys are talking about with 'inplace log' and
 'log_absd(log(absd))' and such. Could you expand?
