The new io library needs some serious profiling and optimization work.
I've already fixed a severe slowdown in _fileio.FileIO's read buffer
allocation algorithm (#4533).

More profiling tests have shown a speed problem in write() files opened
in text mode. For example three str.count() calls are taking up 20% of
the time. The str.count calls can be replaced with an optimized C
function that returns the count of (\r\n, \n, \r) in one pass instead of
three passes.
