Bug Report

I've seen a crash pointing to the [SDLResponseDispatcher clear] method, specifically in the for in loop. It appears that the map is being mutated while being iterated. We should make a local immutable copy, then iterate over that instead.

Reproduction Steps

Unknown

Expected Behavior

No crash

Observed Behavior

Crash
