There are several bugs, but the intention is
-- there should be an uninstaller
-- getVersion/compareVersion should only returns versions if
the named package is still present on disk.
Neither of these work, the first is simply unimplemented and a series of
bugs (28896,64835, 53845) knock out the second .

The registry will close automatically when the refcount on the nsIRegistry
goes to zero. If you release the registry you don't really need to do
flush() -- that will be done automatically when it closes. flush() is more
for cases where you're keeping the registry open for a long while but are
paranoid about making sure changes get physically saved to disk.
