Hi,

The same problem that was reported in issue 1106262 is appearing again on AIX 6.1 (the following error messages appear sometime when runnning python:
sem_trywait: Permission denied
sem_post: Permission denied
sem_destroy: Permission denied)

It can be easily corrected by defining HAVE_BROKEN_POSIX_SEMAPHORES for AIX 6, like it is done for AIX 5.

I attach a patch that does that (I made the patch on Python 2.6.6 but it should apply to Python 2.7 and 3.X as well).

regards

This is also related to issue1234: It was the same issue but concerning AIX 5.2. This patch corrects the problem in the same way but for AIX 6.1.
