IOObjectRelease: passing null? threadsafe?

Hi all,

The docs for IOObjectRelease() are terse.  I'm wondering:

1) How does IOObjectRelease() react to being given null?  Does it do
nothing like free() or crash like CFRelease()?  Yes, I could try, but
I'm looking for an API guarantee one way or the other.

2) Is IOObjectRelease() threadsafe?  Specifically, if I create some
object on the main thread, is it safe to  IOObjectRelease() it from an
Objective-C garbage collector finalize method (which runs on its own thread)?

Thanks,

--
