Test failing: pthread_cancel_test

[gonsie]

The pthread_cancel_test is failing on both Mac (hangs) and Linux (incorrectly marked as passed) systems.

Errors when running test directly on a Mac:

> ./test_axl.sh "-n" "50" "-p" "10" "-c" "1" "pthread"

I am disabling this test for PR #136.

@tonyhutter can you help?
