RubyUDPSocket swallows exceptions

[jagregory]

The RubyUDPSocket implementation swallows exceptions that're raised. For example: line 318.

In my case I was getting Errno::ECONNREFUSED: Connection refused - send(2) exceptions raised, but I couldn't see that in JRuby. I had to switch to MRI to see it.

I'm happy to provide a patch if someone can recommend the best way to raise the exception (I don't know if there's any conventions for doing this).

I think we might have to poke at this to get it right. In general, we have to do some kinda ugly hacks to simulate errno exceptions.

I'll try to reproduce, but perhaps you can provide an example that causes the wrong error?

has been redone lately and should work fine on >= 9.0.5.0
