If the C library thinks it is talking to a pipe, it will switch to block buffering instead of line buffering. It must just think msys is a pipe (since it probably is under the hood).
Normally the IOLBF thing does help there - that means line buffering - but my recommentation is to explicitly call `stdout.flush()` any time it is important in your code. Then you aren't depending on the relatively hidden config value.
