At first I thought, "Ick."  I'd considered this solution already and
rejected it because it was "obviously" horribly inefficient.  But
after reading your message I realized: it's just a logfile. And if
I'm logging so much that the open/close operations cause any
appreciable amount of overhead, I'm probably in trouble anyway.
