Vala threads are based on GLib threads, so they do scale to multicore
systems and they do process in parallel. Contrary to a few other languages,
Vala does not emulate threads, it uses the system threads (with all the
benefits and problems of that).
But pay attention that if your application is not designed for concurrent
processing, it won't matter. For instance, you can block one thread waiting
for the other to finish processing or to free some resource, then you are
just doing sequential processing anyway.
