build failure with nightly

[gregwebs]

I am a new rust user. It seems mioco can only be compiled on nightly due to its usage of features. On nightly I get the following error:

/root/.cargo/registry/src/github.com-88ac128001ac3a9a/mioco-0.4.0/src/coroutine.rs:246:35: 246:47 error: no method named `into_inner` found for type `std::panic::AssertRecoverSafe<F>` in the current scope

Fixed in 0.4.1. Thanks for reporting!

I can't reproduce. I think you might have to update to the latest nightly.

[gregwebs]

Yeah, I was using a docker image that hasn't been updated for 2 weeks. I updated to the latest nightly and it worked.
