I know that normal user doesn't have this problem.
But developers, mainly developers working in terminal, could have.

When large piece of text is loaded to the terminal at the same time, for example, 10000 characters of more, NVDA is hanging up. Also, after a moment, the system hangs up.
The only way is to wait.
NVDA is not reading the text, it's reading pieces of text, then a moment of silence, different piece, silence...

For example, I can call this in ruby by writing

for i in 1..100000
print("A fragment number #{i.to_s} ")
end

Also, we can find this error, when we'll using in terminal app, which writes big pieces of text.
In console commands, like tree, we won't observe this eror, because it isn't loading of text at the same time, there's a while between printing new files.

What is interesting...
The problem is hanging up the all system, you can not open task manager or other apps.

Thank you for help
