Memory leak with evaluating pure JS about pyv8 HOT 3 OPEN

This one would be more correct example

    for i in xrange(10**5):
        with PyV8.JSContext() as ctx:
            ctx.eval(js_code)
        if i % 10000:
            PyV8.JSEngine.collect()
            gc.collect()
            print get_mem()

1. Test 1: Eval empty string

js_code = ''

(741580, 16600)
...
(741580, 16600)

Looks ok!

2. Test 2: Eval small js code

js_code = 'function hello(name) { return "Hello " + name + " from Javascript"; 
}'

(741576, 16596)
(741580, 16636)
(741580, 16644)
...
(747648, 22080)

Then I stopped. It leaks but not so much

3. Test 3: Eval 300Kb js file

js_code = open('bem/touch.bundles/rubric/rubric.xml.js', 
'r').read().decode('utf-8')

(744060, 20436)
(745880, 21796)
(746904, 22272)
...
(1148336, 311196)
(1148336, 311556)

This is huge leak. Test finished with 

PyV8.JSError: JSError: <CALL_AND_RETRY_LAST> Allocation failed - process out of 
memory


Thank you in advance for any help.

I think the workaround posted in my issue might help you as well, see today's
