not exactly...
1) it is used when stepping into a function called by a stub (this is
essential for software watchpointing; since there's hardware watch
pointing on hpux it may be less important)
2) it is used when the current frame's pc is 0
in this case, even if we skip the stub that calls the pthread start
function, the return from the real pthread_start function will still be
zero after you skip the stub, so we still need the stub unwinder to
return a null_frame_id to terminate the unwinding.
