Hmm, I don't know if the port has it, but I did some work on pstack a while
ago to make it work with libthread_db so it at least handles i386 ok. It
needs to be modified to use something like libunwind though or some other
unwinder. And possibly it should use libelf instead of its own ELF-parsing
code.
I see pstack -1.2_1 failing even on i386:
pstack: cannot read context for thread 0x1879f
pstack: failed to read more threads
