Maybe I misunderstood what the OP needed, or the meaning of "rotate a logfile". Another thing that hinted me towards thinking that the solution I posted might be what he needed was when he said "I could store a week (of logs) till overwriting the first log (entry)". In parenthesis I added words that illustrate my interpretation of the problem.

Regarding the locking / efficiency issues, I don't have much to comment since I don't work in an environment that has me concerned about them. Personally though, I would wait until those issues arose before discarding any correct solution.
