I'm using Sentry with koa framework.
What do I do to make each request have its own isolated scope? So I can set some request-specific tags that shouldn't be visible in other requests.

I can't use pushScope because there can be a race condition that results in data from one request being leaked to other requests.

I tried creating separate Hubs for each request, but that's not an elegant solution, and besides, the console breadcrumbs broke.

I tried creating a cloned Scope for each request using Scope.clone(Sentry.getCurrentHub().getScope()) and then passing it in captureException like Sentry.captureException(error, scope). It works fine, but I discovered that Event Processors are not executed for some reason and metadata from the koa request is not added.

On this page I saw an example that used the domain module of node. I haven't tried it, but I suppose that it does something similar to what I'm trying to achieve. The problem is that this module is deprecated and I don't quite fancy these magic "domains". I'd rather have a plain variable with current scope and pass it back and forth.

Any other solutions? Best practices?
