I have explored this problem a little further.  Turns out Eclipse will copy all
the .svn folders to the classes directory if you are not sharing the project
using the subversive plugin.

A quick experiment
Building the ptolemy project without svn sharing: 14 min 03 sec 206 MB copied
Building the ptolemy project with the project shared: 3 min 18 sec  93 MB
copied

You can control what resources are copied at build time in
Preferences->Java->Compiler->Building->Output folder->Filtered resources

Using the following filter
*.launch,.svn,makefile,*.tcl,*.htm,*.html
Building the ptolemy project with the filter and svn: 2 min 08 sec 82 MB copied

You can configure that filter specifically for a project too which the kepler
build system should do automatically.

To close this bug:
1) figure out the best filter for copying resources
2) generate the org.eclipse.jdt.core.prefs and org.eclipse.jdt.launching.prefs
files in the .settings directory whenever the "ant eclipse" build target is run
