pygir (pygir-ctypes) 0.1.0 VS pygtk 2.22.0 VS pygobject 2.26.0

For this benchmark, I use pygir-ctypes 0.1.0, pygtk 2.22.0, pygobject 2.26.0 libraries, and CPython 2.7.1, CPython 3.2 and PyPy 1.4.1 on ArchLinux x86_64. Benchmark shows startup time and memory consumption.

Startup times:

	python2	python3	pypy
interpreter (time PYTHON -c '')	0m0.099s	0m0.077s	0m0.072s
ctypes (PYTHON -m timeit 'import ctypes')	0.885 usec	1.2 usec	1 usec
pygtk (PYTHON -m timeit 'import pygtk; import gtk')	1.79 usec
pygobject (PYTHON -m timeit 'import gi')	0.863 usec
pygir (PYTHON -m timeit 'import gir')	1 usec	1.29 usec	1.1 usec
pygobject (PYTHON -m timeit 'from gi.repository import Gtk')	2.02 usec
pygir (PYTHON -m timeit 'from gir import Gtk')	92.6 usec	86.8 usec	500 usec
example1_pygtk.py (PYTHON -m timeit -n 1 -r 10 'import example1_pygtk as ex; ex.main(True)')	895 usec
example1_pygobject.py (PYTHON -m timeit -n 1 -r 10 'import example1_pygobject as ex; ex.main(True)')	1.15 msec
example1_pygir.py (PYTHON -m timeit -n 1 -r 10 'import example1_pygir as ex; ex.main(True)')	2.38 msec	2.42 msec	38.9 msec
