memory leak

[coke]

Context

Using Zef::Client/Config in a loop leaks memory.

Expected Behavior

Memory usage should stabilize

Actual Behavior

Memory usage increases

Steps to Reproduce

% more mem.raku
    use Zef;
    use Zef::Client;
    use Zef::Config;

    my $chosen-config-file = %*ENV<ZEF_CONFIG_PATH> // Zef::Config::guess-path();
    my $config = Zef::Config::parse-file($chosen-config-file);

    my $zef = Zef::Client.new(:$config);

    my $module="App::Cal";
    loop {
            (state $c++).say

            my $candidates = $zef.find-candidates($module).head;
            my $deps = $zef.list-dependencies($candidates).map(*.identity).cache;
    }
