To make the source code of mc smaller and better understandable. For the 
virtual file system, it nearly makes no sense to provide an mmap() 
method, as most of the filesystems would have to implement it using 
read() anyways.

At least, no vfs other than localfs currently implements the mmap() calls.

Another thing is that mmap() does not work reliably on FreeBSD when 
using it with files in /proc. The Midnight Commander crashes then with a 
SIGBUS error.

There would be two methods less that a vfs implementor has to think about.
