fixing timer buffer problems and python weirdness: a deep dive

this tutorial addresses a subtle but crucial issue in python programming, particularly when dealing with timers and event loops: **timer buffer problems**. these problems arise when you rely on short-lived timers to trigger events in a rapid sequence, and the timing mechanism doesn't execute all events as intended, leading to missed or delayed operations. we'll explore the causes, common scenarios, and effective solutions with code examples and delve into related "weird" python behaviors.

**understanding the problem: the essence of timing imperfections**

at their core, timer buffer problems are a manifestation of the inherent imprecision in computer timing and scheduling. here's a breakdown:

2. **scheduler latency:** the operating system's scheduler is responsible for allocating cpu time to various processes and threads. this scheduling isn't perfectly deterministic. there's a small, but measurable, latency involved in switching between processes or even within the same process. your timer might be set to trigger at, say, exactly 100 milliseconds, but the scheduler might be busy with something else, causing a slight delay (e.g., 102 milliseconds).

3. **event loop overhead:** if you're using an event loop (like `asyncio`, `selectors`, or `gevent`), there's also overhead associated with managing the loop, checking for events, and dispatching callbacks. the event loop itself takes time to execute.

4. **cpu load:** the more your cpu is loaded, the more likely timers are to be delayed. other processes competing for resources directly impact timing precision.

5. **garbage c ...
