AG> Let me just say that this is the single biggest problem that I see AG> with Ruby. To my mind, native threading support is a must for a AG> language to be widely accepted. Ruby's internal threading support has AG> already demonstrated how elgantly Ruby can support common threading AG> patterns - I'd love to see the ability to transparently drop in either AG> Ruby-thread or native thread backends into a Ruby program, without AG> changing anything but the threading class used. I'd also vote to put this near the top of the priority list. thanks, -joe
