// Test for https://github.com/mapbox/mapbox-gl-native/issue/1369
//
// A request for http://example.com is made. This triggers a cache get. While the cache get is
// pending, the request is canceled. This removes it from pending. Then, still while the cache get
// is pending, a second request is made for the same resource. This adds an entry back to pending
// and queues another cache request, even though the first one is still pending. Now both cache
// requests resolve to misses, resulting in two HTTP requests for the same resource. The first one
// will notify as expected, the second one will have bound a DefaultFileRequest* in the lambda that
// gets invalidated by the first notify's pending.erase, and when it gets notified, the crash
// occurs.
