 *     Creates and spawns an isolate that runs the code from the library with
 *  the specified URI.
 *  ...
 *  If the paused parameter is set to true, the isolate will start up in
 *  a paused state, as if by an initial call of
 *  isolate.pause(isolate.pauseCapability). To resume the isolate, call
 *  isolate.resume(isolate.pauseCapability).
 *
 * @description Check that paused parameter with value true cause isolate to
 * start up in a paused state, i.e. isolate entry function is not executed
