Your understanding that such eagerness can become annoying if taken too
far is appreciated. So far I haven't heard anyone suggest you should
move to comp.lang.somewhere-noobs-get-flamed ...

Be aware, however, that the CPython implementation won't net you any
benefit if all threads are CPU-bound, since due to something called the
GIL (global interpreter lock) no two threads will run concurrently.

If you search my past posts on threading you will doubtless find a
couple where I've posted my standard example. I don't want to bore
long-time readers (any more than I normally do) by repeating it yet again.

 Steve
