A project may involve multiple JavaTest-style test suites. For example, the JDK
"langtools" repository, uses the JDK regression test suite and a couple of TCKs.
These are different test suites and cannot share the same JavaTest work directory.

Although I can specify multiple report files for Hudson, I am currently
restricted to a single work directory. This seems an arbitrary restriction. It
means I can only use Hudson to monitor the state of a single JavaTest-style test
suite.
