As we are here, however, I have a question for Robert here: do you think we should support the _ddb() variant of options even in the case DDB is not enabled in the kernel?
It's possible that _ddb() should be spelled _unlocked(), or perhaps _debug(), but neither really suggests what the name should actually imply: using it is safe only in a marginal (debugging) sense, and not in a production code sense. One might also reasonable call them stack_foo_dontusethis().
The _ddb() variants are used in at least two not strictly DDB cases: redzone support, and Solaris memory allocation. And, I guess, the current lock debugging case that we're talking about now, but I'm not sure if those debugging features specifically require DDB in the kernel themselves?
