+##### `[bridge disableJavscriptAlertBoxSafetyTimeout]`
+
+UNSAFE. Speed up bridge message passing by disabling the setTimeout safety check. It is only safe to disable this safety check if you do not call any of the javascript popup box functions (alert, confirm, and prompt). If you call any of these functions from the bridged javascript code, the app will hang.
