---------------------------------------------------------------------

This is a bad idea.  We don't log in the read or write paths.  And line numbers 
can be very useful.  We should revert this.

If someone really cares they can turn it off themselves.  If you really care 
put a commented out version in the log file with them off, and a comment 
telling a user why they might want that.  We have enough log messages that are 
the same, that line numbers are useful.
