return the address of an anonymous glob

I'd be vaguely uncomfortable with the idea that memory could be recycled and at some point you would generate the symbol name more than once.

I would be inclined to extend the symbol name to include the current thread id:

use Config ();

sub gensym () {
    my $id = $Config{useithreads} ? threads->tid . '-' : '';
    my $name = "GEN$t" . $genseq++;
    my $ref = \*{$genpkg . $name};
    delete $$genpkg{$name};
    $ref;
}
