I do understand that. I just think it might be helpful to not
simply say it is forbidden but to enforce it instead of

Considering the enormous amount of plugins there will always be
some plugin developers trying to do forbidden things and if a
user tells them "sometimes vdr restarts but I have no idea why"
it is almost impossible to debug that.

If you take my original two patches you could do

 void cSkinClassicDisplayMessage::Flush(void)
  if (osd)
	     warn: background thread is not allowed to access osd

Otherwise I believe I understand what you propose and it seems
to be a good solution to me.
