Thanks for your replies. Unfortunately, the use of Windows is something
imposed on me - it would not have been my first, second or third choice
for a critical server. I have found something that seems to provide an
adequate workaround for now:

MaxRequestsPerChild 1024

in the httpd.conf kills the server and restarts it sufficiently often
to prevent the out-of-memory condition. *As far as I can tell*, it
also doesn't disturb any Subversion operations that are in progress,
which is much better than a scheduled restart.

It's a bodge that covers up the real underlying memory-leak problem,
but I guess that beats having it exposed...
