[Python-Dev] this is what happens if you freeze all the modules required for startup

They still get read from disk, except that it is the operating system
that does the reading. So what you really save is the access to many
tiny files; something that can also be achieved with the zipfile import.
So I wonder how your all-frozen binary compares to a standard binary
with a python35.zip.

If it is comparable, I'd rather extend on that route, i.e. promote
putting the standard library into a zip file in the default
installation, and also find a way where (say) /usr/bin/hg could
conveniently specify a zip file that will contain the Mercurial
byte code. For example, we could support a -Z option for the interpreter
which would allow to append a zip file to a script that gets put on
sys.path.
