Fixed a failing test on my saio

The added sleep makes this test pass on my saio. I have not heard of
it failing for anyone else, but I figured I'd post this up just in
case someone does have the same problem and this fixes it for them.

Fix HEAD tempurls

HEAD-only tempurls didn't work; tempurl only allowed a HEAD request if
the tempurl was generated for GET or PUT (that is, the method in the
HMAC-signed string was "GET" or "PUT").

The intent of the code was to allow a user with a GET or a PUT tempurl
to also perform a HEAD request; I think the breaking of HEAD tempurls
is just a bug.
