The core.load-stdin test checks Zeek's ability to read scripts from stdin. core.sigterm-regular and core.sigterm-stdin verify that SIGTERM shuts down a Zeek process during normal operation and while reading script content from stdin, respectively. For technical reasons we don't test with SIGINT, as ctrl-c would trigger -- see comments for details.
