Comment (by kcrisman):
I disagree with the analysis as 'needs work'. I understand that this is
annoying, but ppurka is right that this makes something ''mathematically
correct'', or at least more so. " plots extraneous points at z=0" - we
shouldn't be plotting extraneous points. And how many people are going to
be plotting 3d list plots on Sparc? Very unlikely.
There probably is some Numpy internal that causes the interpolations to be
very slow without a default value - at least, I wouldn't be surprised. It
would be worth having someone who understands numpy (not me,
unfortunately) generate a "native example".
That said, it seems like there must be some compromise that we can reach
here for this ticket. Is it possible to add even more {{{# long time}}}
flags to get it under a minute on mark? Also note that if it's 30 seconds
''without'' the patch, that's five times as long as the six seconds above
- so mark would not exactly be a "typical" machine to be talking about
timings on. That's sort of like on my old PPC machine - I'm happy as long
as ''some'' {{{SAGE_TIMEOUT_LONG}}} value works :)
