race conditions in regards to $TX not being in the correct state when the timer fires

In a program using a single event loop, that cannot happen — timers only produce a delay until some time, but do not interrupt other event handlers and timer events are not processed until other callbacks return. There are no races provided that all callbacks return all resources to "safe states" before returning.
