Unblocking a bubbled goroutine from outside the bubble is an error and panics. Currently, some of those panics are regular panics and some are fatal. We use fatal panics in cases where its difficult to panic without leaving something in an inconsistent state. Change the regular panics (channel and timer operations) to be fatal. This makes our behavior more consistent: All bubble violations are always fatal. More importantly, it avoids introducing new, recoverable panics. A motivating example for this change is the context package, which performs channel operations with a mutex held in the expectation that those operations can never panic. These operations can now panic as a result of a bubble violation, potentially leaving a context.Context in an inconsistent state.
