My suggestion is to replace the global id-tree with a list of hwlocks
and iterate over these if we ever get more than one driver registered.
As long as #hwlock-drivers < log(#total-hwlocks) this should be
faster.

I would however argue that clients that would notice any kind of
difference are using the API incorrectly.


Unfortunately this is a somewhat larger change than just slapping DT
support on the framework :/
