While I agree that there is great room for optimization in Squeezer's interception of write(), it doesn't appear to have a noticeable effect in such cases, e.g. in the examples provided by Raymond in the first comment. In my testing, even removing the write() interception entirely doesn't have an effect I can notice.

I'm happy to optimize it anyways, there is plenty of "low hanging fruit" there.
