1.1.1

• Improved the error message received in the parent process if the child process exits without resolving a promise or coroutine returned from the process callback.
• Fixed an issue where killing a child process would not fail any pending promises returned from Process::join(), Process::receive(), or Process::send().
• Fixed regression in 1.1.0 of orphaned child processes resulting from a pool instance being destroyed. Be sure to call Pool::shutdown() to end worker processes gracefully.
