-  // However, the disadvantages of using more than 1 thread are:
-  //   (a) can cause compatibility issues for scripts that rely on side effects
-  //       between runs (such scripts should not be common though).
-  //   (b) increases the memory used by proxy resolving, as each thread will
-  //       duplicate its own script context.
