Ok, seens like a reasonable approach. I don't think attaching is that much
used anyway, so requiring --debug is not an issue, as long as the debugger
show
a clear error message stating that.

The only downside is that it will make debugging generic sharing bugs a lot
harder, as they
will disappear when running under the debugger. This might confuse the users
a lot.
