Unbuffered stdin, bug in docs or implementation?

[guest271314]

This is one of the problems with stdin buffering. The other is related to consuming a specified number of input bytes on a non-seekable input.

I think I have encounted that issue using Python as a Native Messaging host.

The Native Messaging protocol specifies capablility to pass 1MB to the host from client. The hosts exits when 873816 bytes are read from sys.stding.buffer How to read exactly N bytes from stdin in Native Messaging host?.
