Note corona688's comment - the only swpcontext call in main above is one to set context to a function, rather than calling it. main is not swapping context repeatedly.

NAME
IPC::Signal - Utility functions dealing with signals SYNOPSIS
$number = sig_num $name; $name = sig_name $number; sig_translate_setup; $number = $Sig_num{$name}; $name = $Sig_name[$number]; DESCRIPTION
This module contains utility functions for dealing with signals. Nothing is exported by default. sig_num chopped-signal-name Returns the signal number of the signal whose name (sans "SIG") is chopped-signal-name, or undef if there is no such signal. This function is prototyped to take a single scalar argument. sig_name signal-number Returns the chopped signal name (like "HUP") of signal number signal-number, or undef if there is no such signal. This function is prototyped to take a single scalar argument. sig_translate_setup If you want to use the @Sig_name and %Sig_num variables directly you must call sig_translate_setup to initialize them. This isn't nec- essary if you only use the function interfaces sig_name() and sig_num(). This function is prototyped to take no arguments. %Sig_num A hash with chopped signal name keys (like "HUP") and integer signal number values. @Sig_name An array mapping signal numbers to chopped signal names (like "HUP").
