Setting exit code in atexit callback

问题

Is there any way to set exit code in the function registered in atexit module and called on exit? The call to sys.exit(code) produces an error and does not set exit code to the desired value.

d:\>python atexit_test.py
Error in atexit._run_exitfuncs:
Traceback (most recent call last):
  File "atexit_test.py", line 3, in myexit
    sys.exit(2)
SystemExit: 2

d:\>echo %ERRORLEVEL%
0

The contents of atexit_test.py:

def myexit():
  import sys
  sys.exit(2)

import atexit
atexit.register(myexit)

I can prove the test code works in Python 2.7.x (2.7.6 in my case), as reported by @Łukasz Rogalski. So I’ve assumed this to be a bug of Python 3.x and filed a bug report.
