The "universal" cap is useful and important.  it may be enough for
c-torture but other freely available test suites may not be as good a
fit.

I have spent a lot of time running the Ada Compiler Validation suite over
the past year or so on CPU simulators.   There is a fairly large
difference between the longest and shortest tests in this suite.  I have
always regretted that I have had to use a single time/instruction limit
for all tests in the suite.

OTOH it does work and is simpler to manager. :)
