I this situation, is there any way to find what function the hung
process is in? Attach and backtrace it?

While I know I can attach lldb/gdb to a running process, I can't seem to
find a way to interrupt a non-killable process to get control and see
where it is or what it is doing.

and... I just thought I should be looking at dtrace.
