907	signal-tests.scm hangs when port is already in use	felix winkelmann		"The `signal-test.scm` program in the core test-suite may hang indefinitely when port 9999 is already in use. A forked child process calls `tcp-listen` in a separate thread to wait for a termination message from the parent process. If the `tcp-listen` fails, the thread dies (but not the process) and hangs.
