Subject: idiomatic way to pass multiple Procs/lambdas/blocks

I am working on a little syntactical sugar library for 0mq (networking library). One of the things I would like to provide is a set of asynchronous  send/recv methods for transmitting and receiving messages. The method signature would look something like this:

def send message, timeout = -1, callback, errback
end

where...

+timeout+ is the number of seconds to wait before triggering the +errback+ Proc; -1 disables timeouts

+callback+ is the Proc/method/lambda executed upon acknowledged completion

+errback+ is the Proc/method/lambda executed upon timeout


Ruby doesn't allow for passing multiple blocks to a method so I'm faced with passing Procs or methods. 

Is there a more idiomatic way to accomplish my intentions?
