If you set \holdinginserts, of course you should not pass the page
data on to the "real" output routine: it will wack up all its
accounting.  Special penalties are a problem.  Strictly speaking, they
need to get reinserted, then the whole list reprocessed without
holdinginserts, the special routine called, and the holdinginserts

You must _only_ _ever_ use \holdinginserts with _identical_ page
parameters, in particular the same \vsize as when doing the real run.
If you don't, the decisions which inserts to float and which ones to
split (and where) would differ.

Frank will be glad to hear that, I am sure.
