Clean up the queue manually in this test
One more integration test
Guard this test on 1.8.7

Apparently it times out on travis
Facepalm
Increase default continuation timeout on Ruby 1.8
Don't run this test on Rubinius
Remove 1.8 from CI

Bunny clearly is used on 1.8 just fine but
SystemTimer misfires timeouts in the test suite.

1.8 support won't be dropped any time soon but it's not a priority
version to support and we don't have the time to investigate
SystemTimer-specific issues.

JRuby 1.8 mode testing may be a better idea.
Guard these against CI
Correct API reference
Doc corrections
Sleep longer for CI
0.9.0
Back to dev version
