Multiple nodelets can run in parallel on different threads within the
same address space. There is a shared pool of nodelet threads.
Callbacks for a single nodelet may be limited to a single thread, or
may be multithreaded.

That works fine. Create a boost::shared_ptr to a boost::thread in your
onInit() method.
