st: the memory footprint and execution speed of -mf_quadcross()-

[László Sándor <sandorl@gmail.com>]

I checked some of Bill's resources on precision (e.g.
http://blog.stata.com/2012/04/02/the-penultimate-guide-to-precision/),
and -mf_quadcross()- is always mentioned as an option, possibly
overkill, but without much guidance on what the costs of its use might
be in terms of memory or execution speed.

If my code uses the function many times on humungous st_views, was it
a bad idea to use quadcross()? Probably it was — but how bad?

Thanks,

Laszlo

PS: I must wonder about the usefulness of all my questions if they
attract few comments. Thanks for bearing with me anyway.
