default signals handling - cont.

• Use 'info signals SIGHUP' to see just the entry for SIGHUP...
• ...or 'info signals 1' (SIGHUP is signal number 1).
• Numeric values work only up to 15. Above this - use symbolic names.
• Note: some system calls use (now, or used in the past) signals.
  Using them properly under gdb will require telling it not to stop the program when receiving them.
