[Samba] Unanswered question

[Michael Dykstra]

How long does one have to typically wait for an answer to a post?
  Tomorrow my message will have been up a week, and I've gotten no replies.
  It was about whether a file, while it was being written to, could subsequently be opened by another client for reading.  I used a DVR with chasing play as an example.  Didn't seem like that difficult of a question, but maybe it isn't geeky enough for some.  (Or perhaps the answer is "No" and people are too embarrassed to admit Samba can't do it.)
