[New-bugs-announce] [issue16394] Improving tee() memory footprint

[Carsten Milkau]

New submission from Carsten Milkau:

The memory footprint of itertools.tee can be reduced substantially by using a shared buffer for the child iterators (see sample code). If local queues are desired for efficient threading support, they can be combined with a global queue, allowing to constrain the size of local queues.
