Not sure if this is worth reporting..
p = os.popen('sleep 1234')
os.wait3(os.WNOHANG)
os.wait3(os.WNOHANG)
os.wait3(os.WNOHANG)
Notice struct rusage return value. When wait3() succeeds on Linux, but no child was waiting to be reaped, &ru is not updated by the kernel, therefore it is passed uninitialized back to the user, essentially leaking a little bit of stack memory

The original diff is attached here (per the old process) so others can find it, and the PR+fork are closed, as carrying a fork in my GitHub for 4 months has non-zero cost. I'm presently more interested in having a clean GH account than carrying around the baggage of forgotten old patches |
