If you can tell me what you want to happen, I may be able to make
other suggestions.  Do you want the fopen to block until a signal has
been received?  Do you want SIGHUP to cause the process to exit?

It is nearly identical but SIGINT or SIGHUP do not cause the fopen to
be interrupted.  This is because the default signal disposition is to
restart the system calls.
