I tend to keep my system files under CVS, but don't normally turn on 
logging in the files themselves.

I think that once every 20sec is overkill.  Once a minute at the most. 
The file just does not need to change that often, even in an active 
environment.  Besides, once one of the smbd daemons has read it, it'll 
stay in the cache for a while, unless this was also a memory starved 
system.  These numbers sound a bit far-fetched, but anything done 2400 
times a second (3x800), is bound to cause a small load.

Ah well, will note it and try to see if I can test it someday.
