character is read, the processor will yield and try to read the same part again
later. "

where reading a file may return temporary NUL values. "

this case the missing parts are temporarily replaced by NUL values. "
Review comment:
My only concern about replacement is that implies that there was
something else there before. My understanding is the NULs are new content,
added as placeholder to the real content will be replaced by the real content.
So replacement is more like about NUL and new content.
