Perl has excellent support for building threaded applications. See http://perldoc.perl.org/threads.html . I code multi-threaded apps in perl all the time and they utilize my quad-code very efficiently - in fact, my biggest hassle with multithreading is keeping the CPU cooled!
There's also a threads::shared module (http://perldoc.perl.org/threads/shared.html) for handling locks, etc. I'd be hard pressed to imagine better language support for threading.
Hardware, operating systems, and a lot of languages support threading. Granted, it isn't always easy/possible/worth it, but as things currently stand, the only bottleneck is programmers who are too lazy to design their algorithms for parallel execution.
