condition_variable::wait() does not suspend current thread

[LnnrtS]

mutex mtx;
condition_variable cv;
bool condition;

this will busy loop whereas it should wait to be rescheduled by a call to signal() from a different thread

mtx.lock();
while (condition == false)
{
  cv.wait(mtx);
}
mtx.unlock();

I think there something like
scheduler::internal_link_node (list_, node);
missing between these lines

[LnnrtS]

As a quick test I added

{
 scheduler::critical_section scs;
 interrupts::critical_section ics;

 port::this_thread::prepare_suspend ();
 node.thread_->state_ = thread::state::suspended;
}

port::scheduler::reschedule ();

which seems to have fixed the issue.
Not sure if that's the correct fix though..

I don't remember the implementation details now, but normally wait() should relinquish control.

If it does not, it should be fixed.

I don't know how, but entering both critical sections does not look right.
