pselect, as an example, crams the sigmask and size together.  Why not
just do that?  libaio can take care of setting that up.

Yes, I could try that.  It's just another double indirection for no
good reason.

I cna't get this to work - for some reason I always end up with a NULL
sigmask in the kernel.  Nevermind that it leads to really crap code
generation.  I guess for select the latter doesn't matter too much as
everyone sane uses ppoll anyway.
