Looking further at the code, maybe this isn't even needed, since the print-number-table can survive calls to print. But that can get ugly when your printer code also want to call `print` for "unrelated" purposes (e.g. to print debug messages in a side buffer). And I'll stop thinking about interaction with concurrency. Stefan
