Actually I am going to take this back.

When I started working on this, the code was different, but in the final
code I do not see anything that would prevent an interposer to 'try' to
interpose SPNEGO, just like any other mechanism.

A byproduct of trying to be as little intrusive to the current code as
possible I guess :)

However I haven't tested interposing SPNEGO. I don't think there is
anything special that would not make it work with the current code
(Using SPNEGO in front of an interposed mechanism is tested and works
