This code in src/core/Channel.pm:
method send(Channel:D: \item) {
X::Channel::SendOnClosed.new.throw if $!closed;
nqp::push($!queue, nqp::decont(item));
}
Is prone to a race condition; after the 'if $!closed' check, another
thread could close the channel, and either the item being pushed is
silently lost, or things get added to the queue after it was closed.
