hsc 9decf95a09 ecos: specific traps are OK for two benchmarks 
The "except1" and "clockcnv" benchmarks explicitly cause a trap and handle
it in their own trap handler.  This, of course, isn't a bad experiment
outcome.

hsc a0e6ddd519 ecos: fault-space cutoff specific for this campaign 
For the eCos kernel test campaign we define a relatively "special" metric
to compare FI results from different applications:  Instead of aligning
the fault-space dimensions (e.g., by artificially adding "don't care" space
to the right for shorter application variants), we only keep the data
address axis constant.  The rationale behind this is that -- despite the
benchmark applications' run-to-completion behavior -- an operating system's
scheduler usually runs ad infinitum, and that we therefore can extrapolate
from a short application run to any longer period.

In essence, this means we use a failure/experiment-length quotient (ignoring
the Y axis for simplicity, as it is constant in size) to compare
application variants, instead of an absolute failure count.  One important
side effect is that we do not punish any application slowdown with this
metric.  (And simply prolongating non-susceptible program sections with,
e.g., NOPs, seemingly "improves" fault tolerance.)

As we don't know what happens after the "right margin" of the specified
fault space (specified by trace length, or an explicit instruction limit),
we need to do one FI experiment for every register/bit in the end.
