filesystem cache corruption on SIGINT
If webpack-cli is terminated by SIGINT while writing to the filesystem cache (e.g. in watch mode during an incremental rebuild of a project with large external source maps), the filesystem cache will be corrupted and must be erased before webpack will build again.
webpack-cli should hook SIGINT and await a clean exit from compiler.close.
Note that the child processes spawned by e.g. fork-ts-checker-webpack-plugin or thread-loader will hear SIGINT from the parent process, so they'll need to be isolated by spawning the compiler into a detached child process.
/cc @webpack/cli-team should be easy, we should add listener before running webpack and run close when SIGINT happens
It should be added here, right?

process.on("SIGINT", () => {
compiler.close();
});
