I work on a large product that uses the twisted async framework.
And I can assure you the data integrity problem exists in async code as well.
At least in twisted it is easy enough to deferToThread() a background task that
once complete
will continue processing on the foreground thread, we do that for heavy file IO
tasks.
But we offload compute tasks to other processes as using threads in python does
not work
because of the GIL and we have to meet latency targets.
