Doc Type: Bug Fix
Doc Text:
Cause: In TestForkInThread test case from test_thread.py upstream test suite, sys.exit(0) is used instead of os._exit(0). Consequence: Zombie processes are left behind which leave brew builds hanging. Fix: Apply upstream patch to change the TestForkInThread test case Result: Brew builds are not hanging.
