oooops. I'am usually use Ctrl+C to break my program, so this bug was not found

no. under eric3, exception "The socket operation could not completed without
blocking" on line 160 in AsincFile.py (this file is from python's
distribution). It seems, cause of bug is in method of redirection the console
input/output to eric's windows.

Btw, raw_input works fine.

I hate such loops. Usually, if I see the loop, I want to see its condition at
once, I don't want to search for it. In my opinion, "while True"+"break" is
something like "goto"+"if" or even worse.

Anyway, now you know that eric3 use (possibly) little bit buggy mechanism for
redirection of input/output. It's cool:)
