I tested this with the current (bdd370b) vanilla emacs -Q master and
also a slightly older (78c3e14, not quite vanilla) version and I find
that 5 takes about 20 seconds while 4 takes about 30 seconds to print
the whole list (and the next prompt). So, the reason for the behaviour
you reported (and Eli confirmed) might be elsewhere than in
font-locking?
I compiled emacs with
./configure --prefix=/usr/opt --with-x --with-x-toolkit=no --without-rsvg --without-cairo --without-gsettings --with-file-notification=no --without-compress-install
and the beginning of the python buffer is
Python 2.7.10 (default, Jul 4 2015, 12:57:42)
[GCC 4.2.1 Compatible FreeBSD Clang 3.4.1 (tags/RELEASE_34/dot1-final 208032)] on freebsd10

>>> python.el: readline is available
>>> python.el: sent setup code
>>> print(list(range(9999)))
I've also a ~/.pythonrc.py which contains
import rlcompleter, readline
readline.parse_and_bind('tab: complete')
