Comment(by njs):

 Okay, I don't care much either way about the inplace log -- if you guys
 reach a consensus on inplace-plus-comment versus copying, then let me
 know, or I'll just flip a coin :-).

 I think of the names proposed so far, I like `slogdet` best -- among other
 things, it leaves the name `logdet` available for a version that doesn't
 return the sign. Which is probably not worth including in numpy, but I'll
 have it available as a convenience in scikits.sparse.cholmod, since if
 you're using cholmod then you already know that your determinant is
 positive and there's no point in including the sign.
