- * On Windows using `fs.readFileSync(STDIN_FILE_DESCRIPTOR, "utf8")` seems
- * to read 4096 bytes before blocking and never drains to read further data.
- *
- * The investigation on the Emacs thread indicates:
- *
- * > Emacs on MS-Windows uses pipes to communicate with subprocesses; a
- * > pipe on Windows has a 4K buffer. So as soon as Emacs writes more than
- * > 4096 bytes to the pipe, the pipe becomes full, and Emacs then waits for
- * > the subprocess to read its end of the pipe, at which time Emacs will
- * > write the rest of the stuff.
- *
- * Using the nodejs code example for reading from stdin.
