It would be more consistent to have the Windows tests done the same as the 
Posix tests, and it would cause fewer issues with the compiler running out of 
memory, but it _has_ shown actual bugs upon occasion (such as circular 
imports), so I'm a bit divided on the matter, personally. On the whole, I 
agree with you and think that it should be like on Posix, but the difference 
has proven useful from time to time.
