This uses a huge amount of CPU even with no events...

# This uses a huge amount of CPU (it gets auto-killed by the OS after hitting 180% or so)
# even with no filesystem events occurring...

IO::Notification.watch-path('.')\
        .map(*.path)\
        .grep(* ~~ /hhvm_.*\.sock/)\
        .map(*.IO)\ 
        .grep({ .e })\
        .unique(:expires(1))\
        .tap(-> $foo {
                say "$foo.perl() - $foo.e()";
        });
        
sleep(1000);

If I remove the .unique line, it works without a problem.
