/**
 * @assertion bool kill([ProcessSignal signal = ProcessSignal.sigterm ])
 *
 * Kills the process.
 *
 * Where possible, sends the signal to the process. This includes Linux and
 * OS X. The default signal is ProcessSignal.sigterm which will normally
 * terminate the process.
 *
 * On platforms without signal support, including Windows, the call just
 * terminates the process in a platform specific way, and the signal parameter
 * is ignored.
 *
 * Returns true if the signal is successfully delivered to the process.
 * Otherwise the signal could not be sent, usually meaning that the process is
 * already dead.
 *
 * @description Checks that method [kill] doesn't kill the process if this
 * process is successfully completed. The [exitCode] returns a Future which
 * completes with the exit code 0 when the process completes.
