For the record, the "flushfile"s were replaced with code that reads up to a
known %-comment in level 6.0 (dict version 70) printing.  The problem Glenn
alludes to is present in 5.0 and 5.2 printing.  When doing my vetted versions
I replaced the flushfiles with painstakingly-counted skip-counts, like that
used to skip the LaserWriter II NT retrofit code near the top.

There are other gotchas that are still there.  Look for calls to
"setsccinteractive", "waittimeout", and "setdefaulttimeouts".

Or get "macps" from sumex, run it on a command-K file, then diff it :-)
