Tweaking pattern values to improve test results is something that I've
certainly done, and I don't think anyone would object.  I think it's even
a good idea.  As someone (Arend, I think) pointed out, there are a lot
of patterns with the same value, and this doesn't really make sense.
In particular in owl_defendpats, there are 40 patterns with value(35),
including D1401.

Related to this, I think automated tuning of these values is a fine idea.
Likewise, I think automated modification of the owl pattern databases
based on known life & death problems would be useful.
