Changes since v4:
- close fds correctly with code changes added in v3
Chanages since v3:
- abort test-case instead of exiting if heap/mem allocation fails
- Correct test_alloc_zeroed() test case in case of failure
Changes since v2:
- Minor improvements in test_alloc_zeroed() results
Changes since v1:
- Update some more error handling code
