I have no reason to print 3d, but nice to see it working. With things like this and what I believe is all the "crazy" things going on in Linux, I think OpenBSD is a very good alternative to Linux.
For me, the next release will have something like valgrind added to OpenBSD base. IIRC you would use ktrace(1) to look for issues. valgrind is one of the very few reasons I keep Linux around.
