newbuffer (size)	Return a new uninitialized buffer object of size bytes

Performance tuning

alterdot ()	Change dot, vdot, and innerproduct to use accelerated BLAS functions.
restoredot ()	Restore dot, vdot, and innerproduct to the default non-BLAS implementations.
setbufsize (size)	Set the size of the buffer used in ufuncs.
getbufsize ()	Return the size of the buffer used in ufuncs.
