+**Note**: `createSnapshot` does not provide the same isolate protection like the rest of
+isolated-vm. If the script passed to `createSnapshot` uses too much memory the process will crash,
+and if it has an infinite loop it will stall the process. Furthermore newer v8 features may simply
+fail when attempting to take a snapshot that uses them. It is best to snapshot code that only
+defines functions, class, and simple data structures.

 **Please note that versions of nodejs 10.4.0 - 10.9.0 may crash while using the snapshot feature.
