Description

The ImmediateIO and TransactionalIO types implement Sync for all contained Expander<EI> types regardless of if the Expander itself is safe to use across threads.

As the IO types allow retrieving the Expander, this can lead to non-thread safe types being sent across threads as part of the Expander leading to data races.
