sys.stderr and PyErr_WriteUnraisable

[Jan Langer]

Hi all,
I am using Python 2.6 and with the following code I expect a different 
result:

from test.test_support import captured_output
with captured_output("stderr") as stderr:
     def g():
         try:
             g()
         except RuntimeError,e:
             pass
     g()
     print stderr.getvalue()

I expect the ignored exceptions to be printed into the StringIO object 
stderr. With this code there are no warnings on the command line, but 
getvalue() returns nothing.

I looked a little into Python and the warnings are printed from 
PyErr_WriteUnraisable to sys.stderr.

Is this code supposed to work as I expect it or am I missing something?
thanks,
Jan
