Are you saying the following is no good for some reason? 

sub trap_signals {
  local $SIG{CHLD} = \&handler;
  :
}

It seems quite odd to set $SIG{CHLD} in a sub if you want it to have a global effect. But let's say it is a big init function, then you could either silence the critic (since the global effect is desired) or change 

sub init {
   $SIG{CHLD} = ...;
   ... init code ...
}

{
   init()
   ... main code ...
}

to 
sub main {
   ... main code ...
}

{
   local $SIG{CHLD} = ...;
   ... init code ...
   main();
}
