* If a new window station can't be created, keep going anyway. I *think* this is what IntelliJ's fork is doing. Perhaps the window should be marked SW_HIDE in this case? * Rename WINPYDBG to WINPTY_DEBUG. * Add an environment variable WINPTY_SHOW_CONSOLE. If non-empty, the console window is placed on the same window station and is visible. It's intended for testing purposes.
