I compiled Ruby on my system without --enable-pthreads and had a ~15-20% 
performance increase in real-world runs of my application, which makes no use 
of threads or external libraries. I emphasise that this is specific to my 
system (linux kernel 2.6, nptl-only) and my application, but that's still a 
non-insignificant performance increase for a real application run (rather 
than a micro-benchmark).
