It does sound rather as though you're looking for a way to make a sub force its caller to return. You may be interested, amused, and/or horrified to know that Want provides an (undocumented) way to do just this. If you call Want::double_return(), then the next ordinary return will return from the calling sub.

For example, the code: 

use Want;

sub foo {
  print "Entering foo\n";
  bar();
  print "Leaving foo\n";
  return "foo did this";
}

sub bar {
  print "Entering bar\n";
  print "Leaving bar\n";
  Want::double_return();
  return "bar did this";
}

print "About to call foo()\n";
my $r = foo();
print "foo() returned '$r'\n";

prints the following: 
About to call foo()
Entering foo
Entering bar
Leaving bar
foo() returned 'bar did this'

Update: so in your case, you could write 

sub EVENT {
    $kernel->post( shift, event => @_ );
    Want::double_return();
    return;
}
