Yes, that's why I mentioned your name.

This is what I was holding out for. The last time it came up here,
people seemed vehemently opposed to the idea since implementations that
do this (like the Console app and a couple of libraries floating around)
seem to have to poll the console looking for data and that could result
in data loss.
I have had code (not mine) sitting in my Cygwin directory for years
which does this but I couldn't 100% convince myself that the detractors
for this idea weren't right. Does your code work around this?
