Yes, that is it!!

While doing the PROPFIND for the directory with 350 file, the Apache process
grows to over 220MB and then is killed by the Linux OOM killer (my test
machine has only 128KB of real memory). When I run a filesystem checkout,
the svn command never grows over 14MB, so it seems a issue of

What is mod_dav doing that it needs 750KB per file for a PROPFIND? That
really seems very very much?

I like svn very much and every day I use it and discover new features I like
it even more, but this seems to be a real show stopper...
