Before this change, several tests did not detect early deadlocks because they used SIGALRM as the expected signal, and they ran for the full default TIMEOUT seconds. This commit adds a new delayed_exit function to the test skeleton, along with several error-checking wrappers to pthread functions. Additional error checking is introduced into several tests.
