Hi,

I'm pre-compiling multiple javascripts which I later want to execute 
(multiple times, one after the other). Each script accesses an XPConnect 
wrapped XPCOM object which I set with JS_SetUCProperty before calling 
JS_ExecuteScript. It works fine, I have only two questions left:

(*) I copied parts of initialization code from xpcshell.cpp. There I 
found an nsIJSContextStack which I don't understand: when do I need to 
push my context on the stack? I'm currently pushing before calling 
JS_ExecuteScript and popping after. Do I also have to push/pop when 
calling JS_SetUCProperty?

(*) Do I need to create a new context for each compiled javascript? From 
previous newsgroup entries I think I should not. But I only could get it 
running with separate contexts. I compile the scripts with 
JS_CompileUCScript, create an object from the return value with 
JS_NewScriptObject and root the object with JS_AddRoot.

Thanks,
Lukas R
