// is independent of the global from which doTransaction was called.
// To avoid such a leak, we hide the native doTransaction from callers,
// and let each doTransaction call go through this module.
// Doing so ensures that, as long as the transaction is any of the
// PlacesXXXTransaction objects declared in this module, the object
// referenced by the transaction manager has the module itself as global.
