floating point control in extensions
Is there a preferred way to intercept floating point exceptions in
python extensions? I assume one should be careful to restore any
existing error handler. Does python have a standard mechanism for
setting up fpu control words etc?

That at least makes resetting easy when one can do it.
I guessed all Python floating point ops are tested either pre or post
for the correct outcome, but then I tried
so I suppose only the obvious things are tested.
