So it's my understanding that you would like to see atleast the sp
version, and would of course like to see this used with threads.
We currently do not make use of threads in OpenSSL, as in we do not
create them, but it should be multithread safe if you set up
locking.

Your implementation seems to be making use of OpenMP, and it seems
it can be used both with and without OpenMP support and I
understand that it should just work on older compilers that don't
support it.  There seem to be various compilers that support it
including gcc and Microsoft Visual C++.

I'm wondering if we should also use OpenMP.  It clearly looks very
useful.
