> What would be a catastrophic flaw? How the tests could prevent it?

I experienced a build/test failure making .31, and it showed up in the
test results.

The point is rather whether not testing is viable.  If one doesn't test
one has no confidence at all that it has been made correctly.  (I grant
that just looking at the tables and comparing gross numbers does little
to create much confidence.  But not doing so cannot be better!)  This
isn't ed we're making here.  It's a HUGE package with a known history of
security vulnerabilities.  I imagine there are any number of possibile
ways for an incorrect compilation to compound those vulnerabilities.

No argument there, and I think it will continue to improve.

Of course it is, and it shouldn't be removed.  The question remains:
with such a large project, is it right suggest avoiding running the 
tests for 110 SBU's can be avoided without consequences.

Some tests, plural, DO timeout, even on an i7-940, and the consequences
of not having networking running are terrible--like 57 orphaned JVM's
never cleaned-up and left running!  That statement needs strengthening.
"Networking must be running."
