Agreed. Rather have a new function that uses mmap() ie. mmap_readfile()
or whatever the name would be for it.
I'd like to hear Sascha's reasoning for adding mmap() in the first place.
Maybe he had something special in his mind?

optimize fpassthru/readfile to use mmap instead of fread
which especially increases speed on large files."
