our is not supposed to be a global(ly visible) variable and hence should be reclaimed at the same time as my $foo

I have to disagree. our creates a lexical alias for the global variable (stored in the symbol table).

use Devel::Peek;

our $foo;
Dump $foo;
Dump $main::foo;

__END__
SV = NULL(0x0) at 0x24bfdc4
  REFCNT = 1
  FLAGS = ()
SV = NULL(0x0) at 0x24bfdc4
  REFCNT = 1
  FLAGS = ()

The alias isn't globally visible, but there's still a global variable behind it. This is how it should be. Consider this:

use strict;

{
  our $foo = 'foo';
  our $bar = 'bar';
}
{
  our $foo;
  print $foo;
  print $main::bar;
}

__END__
foobar
