Yeah, non blocking (true multi-threading) is considered to introduce 
complexity so it probably default to non true multi-thread.
I know with jruby this is (probably) not the case, and with ffi you can 
set a method as non blocking, though it appears to have an annoying 
syntax, and would only be non-blocking with MRI 1.9+:
