Hi,

I do the following:

hythread_suspend_disable();
<do unsafe actions>
hysem_wait(semaphore);
<do unsafe actions>
hythread_suspend_enable();

By saying hythread_suspend_disable(); I expect the thread can't be
suspended until hythread_suspend_enable() is called. But hysem_wait()
resets disabled mode and enables thread suspension. As a result GC can
happen when it must not. hysem_wait is based on conditional variables
so the same can happen when conditional variables is used.

Do you see the problem here? Or I miss something?

Thanks
Evgueni
