Given how immensely annoying such an API would be, and that it would
require every plugin to have a printf implementation to actually be
useful... which in the real world probably means they simply won't do
the RT safe thing at all... no. Ruining the API for this dubiously
useful border case would be ridiculous.
What it suggests is that printing in realtime is not worth it. I'm all
ears for examples to prove otherwise...
