Should OnRenderProcessTerminated cancel pending tasks?

[campersau]

When the render process crashes all pending tasks are never going to complete.
Should CefSharp cancel them?
What about new pending tasks that are created on browsers which crashed?
When a new page gets loaded the browser is no longer in a crashed state at least for OOM errors.

An OOM crash can be reproduced by executing this code:

let array1 = [];
for (let i = 0; i < 10000000; i++) {
    let array2 = [];
    for (let j = 0; j < 10000000; j++) {
        array2.push('a'.repeat(100000000));
    }
    array1.push(array2);
}

Here is naive implementation of what I am asking for: campersau@f380d39

Otherwise users need to always make sure to pass a timeout to avoid an infinite wait.

Yes.

Ideally when a V8 context is destroyed we would cancel any pending tasks, that's quite a bit more complex though.

Any sort of render process crash should cancel tasks.

There is a specific URL to simulate a render process crash listed in https://bitbucket.org/chromiumembedded/cef/wiki/CrashReporting.md#markdown-header-testing

Pr would be most welcome.
