Interesting... Are you implying, the debugging code makes no difference,
or are genuinly asking?
There are additional steps in the code, that are only done when
the define is on. Does not look like much in libthr, but c_r's
uthread/uthread_mutex.c seems quite affected, for example. And you know
it, of course...
= Regardless, it would first need to be in -current, not -stable.
I thought, the debugging features (WITNESS INVARIANTS) are always on in
-current, but are turned off in -stable for maximum performance. Is that
no longer true?
