If you've got JUnit tests that shows it in use, feel free to donate it -
we're more than happy to facilitate other people's use-cases.

As it happens we're on the cusp of releasing PicoContainer 3, but you may
have a strong preference for doing this for PicoContainer 2.0, and we're
happy with cooperating with that agenda too.  Patch-files for Pico2
(imperfect Subversion world).  A Github fork (and pull request) for
PicoContainer 3, if your happy with an implicit delay on release.
