Disassociating write to screen - command prompt from execution flow

[ananda vardhana]

Hello,

I am writing to the screen using wprintf() and wcout() at various points in my app in a big while(). Example:

while(1) {
wprintf(L"Hello\n");
wcout << L"Hello again\n";
WriteToAfile(L"Abcdefgh\n");
}

When this is happening if I click on the screen the display freezes that is fine that is what I want but I want the while loop to continue and the write to happen. One solution is creating a thread but then I might end up with creating millions of threads so that is not a viable solution. So is there a way to Disassociate the write to the screen from program execution? In other words if the user clicks and freezes the screen WriteToAFile() should continue unfazed. If creating a write thread is the only solution is there a easy way to prevent millions of thread being created? I would say detect the mouse click and not create any more threads until user hits an ESC to unclick it. I have enclosed a sample program I wrote to demo it. If you can kindly suggest the way to disassociate that would be really very helpful.
