[issue29842] Make Executor.map work with infinite/large inputs correctly

In any event, sorry to be a pain, but is there any way to get some movement on this issue? One person reviewed the code with no significant concerns to address. There have been a duplicate (#30323) and closely related (#34168) issues opened that this would address; I'd really like to see Executor.map made more bulletproof against cases that plain map handles with equanimity.

Even if it's not applied as is, something similar (with prefetch count defaults tweaked, or, at the expense of code complexity, a separate worker thread to perform the prefetch to address Max's concerns) would be a vast improvement over the status quo.
