The FreeBSD native threads stuff also does some nasty grovelling in the pthread private data structure for the stack address and stack size. I know these are handled by _np functions on BSD/OS, but they need to be included in any FreeBSD discussion of the pthreads APIs that we need. I suspect this sort of discussion will also apply to NetBSD and OpenBSD. > It's used sparingly in a couple of places with varying levels of functional > importance like the GC and during thread creation time (new threads are > suspended only to be woken up by the spawning function after the stack is > attach to the VM), etc... > > I'm struggling with OpenMotif issues right now and I'm kind of wondering > why the current OpenMotif port is a release version behind what's being > offered at their site ? Not sure.
