Originally created by @were on GitHub (Aug 8, 2021).

Windows Terminal version (or Windows build number)

1.9.1942.0

Other Software

WSL or SSH. Run on Linux. I did not try to replicate it on pure PowerShell but I think it should be very similar.

Steps to reproduce

Writing a code that dumps excessive logs to stdout.

int main() {
  while (true) {
    std::cout << "Hellow world" << std::endl;
  }
}

Expected Behavior

If I type Ctrl-C, it should stop immediately.

Actual Behavior

If need to type Ctrl-C repeatedly until it stops. It seems the thread that listens the keyboard signal is starving.
This issue is not happening in PowerShell terminal (I mean just run PowerShell from Start menu, not from Windows Terminal tab).

I think this might be related to issue #2141.

#2141 might be the root cause, but at the very least this is definitely a /dup of #6258. Thanks!
