Nope, else it's a bug :)

It should already be the default. To get the whole system, see lstopo
--help: --whole-system

I've wondered how to implement topology changes indeed. AIX does have a
SIGRECONFIG signal for this, I don't know any support from other OSes.
that'd mean having to poll for changes, how often, and in which context?
(another thread? an explicit polling request from the application?). I'd
rather avoid the thread usage and just let the application decide both
how often and in which context. In other words, actually maybe all we
need is a function to compare two topologies?
