This patch set adds validation tests for the signal manager and fixes a potential issue with a recursion in the ASR handling. The main issue is that _Signal_Action_handler() used rtems_task_mode() to save, set, and restore the task mode during ASR processing. This is effectively a recursive call to thread dispatching which may result in the next level of ASR processing.
