| * This sample test aims to check the following assertion: |
| * |
| * The new thread inherits is signal mask from the calling thread, |
| * and has no pending signal at creation time. |
| |
| * The steps are: |
| * 1. In main(), create a signal mask with a few signals in the set (SIGUSR1 and SIGUSR2). |
| * 2. Raise those signals in main. These signals now should be pending. |
| * 3. Create a thread using pthread_create(). |
| * 4. The thread should have the same signal mask, but no signals should be pending. |
