/**
 * @assertion Spawning an isolate is accomplished via what is syntactically an
 * ordinary library call, invoking one of the functions spawnUri() or spawnFunction()
 * defined in the dart:isolate library.
 * However, such calls  have the  semantic effect of creating a new isolate with
 * its own memory and thread of control.
 * @description Checks that a new isolate created with spawnFunction()
 * has its own memory which is not shared with other isolates, using a top-level
 * variable to showcase it.
