Yes, same here (2.2.2 and 2.3 from CVS both built locally with Mdk 9.0).

Besides the .py and .pyc for all the modules, there's a few more files
that 2.3 is opening and 2.2 isn't:

early on:
open("/usr/lib/libstdc++.so.5", O_RDONLY) = 3
open("/lib/libgcc_s.so.1", O_RDONLY)    = 3

in the midst of the imports (just before encodings/__init__.py):
open("/usr/share/locale/locale.alias", O_RDONLY) = 3
open("/usr/share/locale/en_US/LC_CTYPE", O_RDONLY) = 3
