Using the svn trunk as of friday afternoon, this results in a PDF file containing the world "Hello". " world!" is missing for some reason. There is no warning in the log file.

In general, tex.[s]print do not work in callbacks at the moment, and that may be the wisest thing, because the state of the interpreter can be a bit unpredictable at times. An exception could be made for process_input_buffer because as you say, it is very useful there. But I cannot do that right now because the C code behind tex.print does not support nesting yet. I'll add a tracker item. Best wishes, Taco
