In some use cases (https://gist.github.com/4306474) it's possible to get a really confusing error message (throw: all goroutines are asleep - deadlock!) if a port is in use when Wendy attempts to use it. Need to investigate and make sure that this is just me being dumb in how I wrote the test script, not a shortcoming of Wendy's.
throw: all goroutines are asleep - deadlock!
This should no longer be an issue as of beta1
