* To be called from JavaScript only.
*
* Synchronously loads and evaluates the js file located at
* aResourceURI with a new, fully privileged global object.
*
* If 'targetObj' is specified and equal to null, returns the
* module's global object. Otherwise (if 'targetObj' is not
* specified, or 'targetObj' is != null) looks for a property
* 'EXPORTED_SYMBOLS' on the new global object. 'EXPORTED_SYMBOLS'
* is expected to be an array of strings identifying properties on
* the global object. These properties will be installed as
* properties on 'targetObj', or, if 'targetObj' is not specified,
* on the caller's global object. If 'EXPORTED_SYMBOLS' is not
* found, an error is thrown.
*
* @param resourceURI A resource:// URI string to load the module from.
* @param targetObj the object to install the exported properties on.
* If this parameter is a primitive value, this method throws
* an exception.
* @returns the module code's global object.
*
* The implementation maintains a hash of registryLocation->global obj.
* Subsequent invocations of importModule with 'registryLocation'
* pointing to the same file will not cause the module to be re-evaluated,
* but the symbols in EXPORTED_SYMBOLS will be exported into the
* specified target object and the global object returned as above.
*
* (This comment is duplicated to nsIXPCComponents_Utils.)
