It's not clear to me how anything like that in the system console could affect Blender. Could you be more clear about what you mean with system console? Just to be sure we're talking about the same thing.
In case we are, this would be a Windows only issue.

Even though unix Blender is launched from Terminal, window menu doesn't show "Toggle system console". It's only for windows.

As soon as you cancel selection in console, execution continues

I may add, that when I quit Blender during debugging session (MSVC), console will wait for key press. I am not able to start new session until I make key press.

I haven't noticed that. I'll change description. And also I changed the title, as I was mistaken about the crash

If there's no crash, I wouldn't count this as a bug.
The console on windows always blocks if text is selected, and every software I know behaves like this.

I believe this is also used as a "feature" by some, in order to pause rendering.

I can confirn that it is a bug. As I mentioned in the description of the problem, in blender 2.69 and in older versions worked with the same set up that in recent versions stops working

I just tried this on Windows 7 64 bit with Blender 2.68, and it hangs just the same when opening a file while selecting something in the console.

This is not a bug; Windows blocks stdout when selecting something in the console, and since Blender logs something to the console on loading it has to wait.
This is intended.

The description still mentions a crash, but you said you were mistaken, so I see nothing to do here.

Okay now... This is strange. I just downloaded 2.68 and I did the tests. It turns out that with 2.68 version, it allows you to save, but not to open files, while in 2.7 and newer can't save nor open

@Tabra This is caused by the QuickEdit-Mode of the console and is unrelated to Blender. Perhaps some versions of Blender do not print to stdout when saving the file, which would avoid the freeze.

Just out of curiosity, even if this is by design, I wonder if you know if it would be possible to prevent Windows from doing this, or is it something that's super hard-coded into the system?
