Some of the screens to be captured occured at times when file writing

adequate for MOST purposes, but SOME screens can NOT be captured that way,
since by the time that the system was stable, the screen contents were no
longer the same. Hence "copy to RAM bufer, and THEN write once safe".
For example,... you want to show the screen contents when it is halfway
through XORing the bytes.
4000 byte
buffer when the "magic" key combo was pressed, and then poll for
Poll? How did you do this, and why was it necessary? I've written
screen capture programs before and I just dump straight to a file...
