+Proof General will try to configure itself to update the display of
+tracing output infrequently when the prover is producing rapid,
+perhaps voluminous, output.  This counteracts the situation that

+to fontify and refresh the display as fast as output appears.
+See `proof-trace-output-slow-catchup' for setting.
