The problem is that Windows is a toy operating system with a toy file
system that does not allow the deletion of open files.  I think Unix 
had this solved in the 1970's :-)

I'm not sure about a workaround here, since ant is a java process and
kepler-tasks.jar is in the CLASSPATH.

If we had tests of the build system, presumably this bug would have been
caught.
