Issue Description:
On Alamofire's feature/async-handlers branch (Xcode 13.2 required), running more than one of the new async tests at once causes multiple thread sanitizer warnings. Running the entire DataConcurrencyTests suite of ten tests causes 46 issues. I've put them in this gist: https://gist.github.com/jshier/8c9c7190e1166c28df567fe869355e49
To run Alamofire's tests you'll also need to install and run our test server (brew install alamofire/alamofire/firewalk && firewall &).
