That's right, and I don't currently run those tests.

But can a person who changes something in scipy.linalg choose not to
run those tests?

I don't understand your argument.  You propose to make 'fast' be the
thing that developers run before committing changes to SVN and then
argue that this will lead to more tests being run?  Who runs the slow

If you make the default too slow, the *de facto default* will be
'fast' or None :)

Passing 'nosetests scipy' should be the standard for modifications to
scipy.  It should be as comprehensive as possible while running in ~60
seconds.  We can have an additional suite of 'slow' tests for
releases, build bots, and paranoid developers.
