Another option is to use WriteConsoleOutput() function, which takes combined
character and attribute (color) data. But there is one problem with it - it
won't change the cursor position. So we'll have to change it manually. Which
means calling GetConsoleCursorInfo() to get current cursor position and
SetConsoleCursorPosition() to change it.
It's still not thread-safe. On the other hand, if we DO use locking, this
solution offers shortest locktime, because character/color buffer is prepared
outside of lock, function locks only to write data into the console and move
the cursor, which should be faster than writing a string and changing color
attribute a few times (current solution) or writing one string and then setting
console attributes a few times (the FillConsoleOutputAttribute solution).
FillConsoleOutputAttribute has an advantage of writing meaningful text data in
both implementations (with or without locking), because the presence of a lock
only affects the way it colorizes text (it may colorize wrong characters in
concurrent mode, but at least text will be intact).
