Running zlibs own tests is unlikely to be too helpful. I'd be quite
happy to run any JDK tests you have and there are also testcases in
Apache Harmony for the related Java APIs.  I'm curious to understand
just what level of testing is already done though?

I think this is simply about currency.  Getting fixes from other
projects usually has a list of drag-alongs.   So the closer you can keep
to their latest production level the smaller that list is , and
consequently the lower the risk is,  when you need a specific fix

Agreed - I can imagine why zlib was embedded originally but I can't see
why that should continue. It seem that the right direction is to remove
the embedded code and rely on the platform providing the support.
