   4 Subject: [PATCH] fix latent bug in signal handling, per POSIX calling exit()
   5  in signal handler is not safe.  Use _exit() instead.  Also, detect the user
   6  signal SIGINT for the case of server needing two invocations to stop server
   7  threads.  Note: the server threads still need some work from graceful
   8  termination with a single ctrl-c
