Redo handling of unhandled exceptions in async execution
Here is the problem: noexcept looses the call stack. That is, unlike an unhandled exception, if noexcept is tripped, then you won't see the place where it was thrown. In this new implementation we now have noexcept only on the task thunk. And the task is called via a thunk only in case of async execution. This means that if we are executing serially (-j 1), then this will be an unhandled exception, not noexcept. Hopefully will be a bit easier to debug.
