This is C++ threads. I didn't see anything like that for C11 threads.


<sigh> How does this help a user with portable C++ code move an application
to
RTEMS? I see this requiring users track the C++ instances with some form of
run-time profile and none of that will be portable. They seem to be focused
on
parallel work loads than real-time threads with specific run-time profiles.


I would recommend unlimited objects as a first measure.

But we have asked users who care to count object instances for years. Just
making it clear they are C11 threads. They shouldn't care how they are
implemented
