 *	name, i.e. SIGQUIT is known as "QUIT".
 *	Gaps in the signal numbers (up to NSIG) are filled in with NUMnn,
 *	etc., where nn is the actual signal number (e.g. NUM37).

 *	within that list and the SIG_NAME list match, so it's easy to compute
 *	the signal name from a number or vice versa at the price of a small
 *	dynamic linear lookup. 
 *	Duplicates are allowed, but are moved to the end of the list.
 *	The signal number corresponding to sig_name[i] is sig_number[i].
 *	if (i < NSIG) then sig_number[i] == i.  
 *	The last element is 0, corresponding to the 0 at the end of
 *	the sig_name list.
