hese changes plumb basic support for cancellation through the engine. Two types of cancellation are supported for all engine operations: - Cancellation, which waits for the operation to drive itself to a safe point before the operation returns, and - Termination, which does not wait for the operation to drive itself to a safe opint for the operation returns. When updating local or managed stacks, a single ^C triggers cancellation of any running operation; a second ^C will trigger termination. Fixes #513, #1077.
