This reduces the number of OS writes to the working copy, particularly
when svn:keywords, svn:eol-style or ra_dav are in use.  It's difficult
to quantify as it seems to depend very much on the hardware, some of
my tests show small improvements, others show dramatic (75%) reduction
in CPU usage.  It will be interesting to see what change, if any,
others see.
