rt::io::net::tcp methods may throw SIGABRT

[jedestep]

While migrating my code over to this new TCP library, I discovered it'll throw a SIGABRT whenever attempting to connect to an address. It appears to be coming from any method which can raise a condition (i.e. Listener::bind and TcpStream::connect).

Platform is OSX 10.8 x86_64.

At a guess, I imagine this is simply due to calls to rtabort! because rt::io requires the new runtime, which is not turned on.

@brson said in IRC that the TCP library depends on the new runtime, which isn't finished yet. This is why you are getting these aborts. If you want to help shake out the bugs in the new runtime, try running your code with RUST_NEWRT=1.
