File that has records constantly being added and deleted

Here's the situation:
We have a file. Any arbitrary number of jobs can put records into the file; a single dedicated job reads the records, in arrival sequence, processes them, and deletes them. We thus have a file that rarely has more than a few active records, but accumulates lots and lots of deleted ones.
Is there a way to squeeze out deleted records without having to grab an exclusive lock on the file? Or would it be more sensible to set it to re-use deleted records, and modify the processing program to read by key? Or are there other ideas?
