Snapshots and forks in bursts no longer wait running

A snapshot or a fork of a running sandbox now stops it at once, so the snapshot, or the fork's copies, hold the memory of the moment you asked, and then waits for its turn at the server's disk with the sandbox stopped. Before, it waited for that turn with the sandbox still running, and a burst on one server could take tens of seconds each, the sandbox changing all the while. A sandbox whose time limit or funded time ends soon, on a busy server, still waits running and stops at its turn, as before. See products.
