For both 2.6 and 2.7 the pythonw and python executables in bin execute Python.app/Contents/MacOS/Python, the latter is the real executable. The only difference between 2.6 and 2.7 is how the executable inside Python.app is started: 2.6 uses execv() to start the real executable while 2.7 uses posix_spawn (when available, it falls back to execv on older versions of OSX). What happens when you install Python using the beta installer at python.org? Does that behave in the same way as the version you installed yourself? I'm currently running 10.6, I'll try to find some time to test in a 10.5 VM later this week. Could you please file an issue in the python bugtracker to ensure that this issue doesn't get lost?
