2. say that across all platforms python supports given functionality on, said functionality needs to have functionally identical results given identical input. in this case, the flush+seek workaround needs to be utilized on all cpythons linked with msvscrt in a manner transparent to the user.
It seems like we can work around this more easily than that, considering that flush and seek are available from Twisted; the file object causing problems in the tests is being returned from the open() method of a FilePath object, if I understand it correctly. FilePath could include the workaround far in advance of Python deciding to.
oh, it makes perfect sense to have a workaround in twisted, i'm not suggesting otherwise. however, it should be just that - a temporary workaround until cpython has a fix for the issue, because (outside of the offending libc implementation), that is the right place to fix it. -p
