We do not properly prevent fibers from being resumed across threads. Here's a user-provided example:

https://gist.github.com/2889369

We produce "double resume" errors when we should produce "across threads" error.

Here's an attempt at a patch that does not appear to solve the problem: https://gist.github.com/2890071

@MSNexploder

1.7.20 and 9.0.0.0.pre both produce correct "across threads" errors.

@headius headius added this to the JRuby 1.7.20 milestone Jun 5, 2015
