Would you not want to avoid that when there has not been a record
since last time you closed it?

I'd be thinking about something like this (very untested)

do forever
  'peekto'
  'callpipe (end \)',
     '\ i: fanin | g: gate',
     '\ *:',
     '| g:',
     '| >> output file a',
     '\ literal +30 | delay | g:'
end
