[Numpy-discussion] RC2 to be released Friday

I'm going to have to put off release of rc2 for Friday.  I'm just too 
busy right now.  That might help us get some speed-ups into the 
NOBUFFER_UFUNCLOOP code as well.

My speed-up ideas are:

1) Only keep track of 1 set of coordinates instead of self->nargs sets 
(1 for each iterator).
2) Keep track of the dataptr for each iterator in the bufptr array (so a 
copy isn't necessary)
3) Not increment the index on each iterator separately.

All of these changes will be made directly in the NOBUFFER_UFUNCLOOP code. 

More generally, it would be nice to take these ideas and push them into 
other areas of the code --- perhaps through the multi-iterator that is 
already present.  Probably, this will have to wait until 1.0.1 though.
