Aczkolwiek

https://en.wikipedia.org/wiki/Mmap

"The original design of memory mapped files came from the TOPS-20
operating system.
mmap and associated systems calls were designed as part of the
Berkeley Software Distribution (BSD) version of Unix.
Their API was already described in the 4.2BSD System Manual, even
though it was neither implemented in that release, nor in 4.3BSD.[1]

Sun Microsystems had implemented this very API, though, in their SunOS
operating system.
The BSD developers at U.C. Berkeley requested Sun to donate its
implementation, but these talks never led to any transfer of code;

4.3BSD-Reno was shipped instead with an implementation based on the
virtual memory system of Mach.[2]"

To moze da sie bez mmap.
W dodatku ... wczesne implementacje nie mialy jakiegos limitu na
wielkosc pamieci uzywanej?
Np 16KB :-)
Wiec mozna normalnie wczytac do pamieci.
