Yep. I definitely agree with this, and streaming certainly becomes
imperative in this case.

Output streaming really seems to require application-level explicit code.

Input streaming can (generally) be handled two ways: (1) You can do it
yourself. (2) You can memory map the file and let the paging system work for

Is there a compelling reason NOT to rely on memory mapping for input files?
Do all of the target operating systems now support memory mapping, or is it
unavailable on some platforms?

Thanks again. I recognize that this is a naive question, and I appreciate
your time in responding.
