Main binary must be linked against libpthread if any DSO mgiht depend on
anyone have any familarity of how the interpreter works?

wondering if it does wierd things with sigaltstack, etc to handle code

Don't know too much about signalstack. All I can say is that it (Ruby)
does lightweight threading using alarm(3), and it scans the stack for 
memory references (conservative garbage collection).
