All right then, no need to hurry.

I'm not sure either. I used to use --with-javascript=dynamic a while ago, but 
I stopped using it when I managed to unbreak static linking.

I suppose these have been added in your recent patches. I have not yet looked 
at them, currently I have simply defined an EXPORT_DYNAMIC_OPTION variable, 
which is set to "" unless dynamic javascript loading is requred. I will not 
commit it though, since the work you are doing will obsolete this change.
