Unable to create different context

[GoogleCodeExporter]

I’m using PyV8 as a base for my Sublime Text plugins. I’ve successfully 
used PyV8 on my Emmet plugin, but now I’m creating a new plugin and have 
issues with JS context.

Each plugin creates it’s own JSContext instance that should keep data and 
exist during plugin lifetime. Context is initiated as follows:

self._ctx = PyV8.JSContext() self._ctx.enter() self._ctx.eval('...JS source code...')

The problem is that PyV8 seems to have just one JS context which is shared 
across plugins. 

For example, if Sublime Text loads plugin A and then B, I can access JS methods 
of B plugin but not A (error is: `AttributeError: '[object global]' object has 
no attribute 'XXX'`). If I explicitly reload plugin A (e.g. re-initiate it) I 
can access methods of A but not B.

Here’s how JSContext is used in plugin:

In the recent API changes, V8 engine has a lot of different behaviors :( I 
would fix it soon

I did some research on this: such behaviour is correct since V8 creates 
contexts as stacks and uses the latest one globally. 

I made a workaround for this problem: I explicitly enter required context 
whenever I need to do something:

Works fine so far.
