io.popen() without popup windows

[zetah]

When executing lua command with io.popen(), on Linux it's silent, but on Windows cli windows pops up and hides quickly afterwards.
Same for os.execute()

Is there a way to hide window popups?

So it can be avoided by using extman lua script and additional dll, then use spawner.popen(). But unfortunately it gets funky for non trivial command lines. For example running Saxon Query (.NET) hangs Scite, while io.popen() finishes as expected. Then it blocks GUI, but it's better then nothing.
