Sorry, I can't hold it back.
Not only that tasklets are smaller than expected, they
are also really fast.
I was stunned when I measured switching speed on an AMD Athlon XP 1500+
machine. A python script switched tasklets 1,000,000 times. The usual
Python call overhead was included. I measured this without switching and
got about 0.3 seconds. That means: Context switching by an automated,
internal scheduler without the interpreter overhead comes at the same
cost as a Python function call.
