New Post: MemoryLeak despite disposing of V8 Script Engines

I have at most 10-15 scripts active at a time. For each script, I create a separate V8Runtime and create an engine off of that. I compile the script, too. So for each script I have a Tuple<V8Runtime, V8Engine, V8Script>.

At first I did not create an explicit runtime and used the V8Engine constructor. But in an effort to solve this problem I added the explicit V8Runtime so that I could dispose of it explicitly.

So now, after a particular script receives 250 callbacks, I will completely dispose of the script, engine, and runtime, then build them back up again. I was hoping whatever was leaking would get cleaned up that way, but it didn't make any difference.

I could instead keep a pool of V8Runtimes and reuse them and see if that helps. But if I do that, I have a question. These are all long-running scripts, because they are waiting for a callback initiated by managed code. But I want each script to be isolated and not collide any globals between them. I also would like them to execute in parallel if possible -- because each one really has nothing to do with any of the others, so serializing execution of them would be silly and a possible bottleneck for me. So, the question is, if two V8Engines share the same V8Runtime, will they still be isolated from each other in that regard?
