OTOH, if you really wanted to do this
Generators and iterators are laziness where you tend to need laziness the
most. Generator expressions are tiny generators - more full fledged
generators are supported.
Python probably won't have laziness at its core ever, but it's nice having
a dose of it. IOW, you probably won't be able to writ
Hello All,
Could one say that generator expressions and functions are Python way of
introducing Lazy concept?

30% of how many cores? If that's a quad-core processor, that could
indicate one core completely pegged plus a little usage elsewhere.

Thanks Daniel, that's interesting. Unfortunately there is no sensible
code I can post because this only happens when I make a specific call
into the vendors SDK. I can exercise my own code in the extension
without a problem. The python test calling code is doing practically
nothing. I make 3 calls
Add a time.sleep(0) call to all your loops. Multithreading in Python
is a cooperative cross platform threading simulation if you have tight
loops Python won't task switch until you make a system call.
Potentially preventing internal library variables from being updated.

Hi all,
I've been a long time user of Python and written many extensions but
this problem has me stumped.
I've written a straight forward extension that wraps a vendors SDK for a
video capture card. All works well except that in the Python thread on
which I call the extension, after certain calls

That's the point. If a simple example (6 lines) can demonstrate the
concept, why spending "ten pages" to explain it. My experience
