JobServer: synchronization issues
...
Synchronize re-sending jobs in sendPendingExperimentData() and modifying
(or indirectly, via getDone() and the campaign, deleting) jobs in the
m_runningJobs queue.
a) sendPendingExperimentData needs an intact job to serialize and send it.
b) After moving the job to m_doneJobs, it may be retrieved and deleted
by the campaign at any time.
Additionally, receiving a result overwrites the job's contents. This
already may cause breakage in sendPendingExperimentData (a).

ecos: use multiple intermediate states to speed up experiments (disabled)
...
This modification creates and uses multiple intermediate snapshot states
(one every 1,000,000 instructions) to fast-forward to the FI site.
Unfortunately this doesn't work yet; the trace seems to change in many (not
all!) cases we do this. One possible cause could be an incorrect
(off-by-one or alike?) restoration of the serial device timers, and
therefore an earlier/later transition to "output buffer empty", resulting
in eCos' serial putc function needing a different amount of polling loop
iterations. Needs more investigation.

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.)

simulate the configured baud rate; these timers cease to work after
repeated misuse from the Fail/Bochs bridge.

bochs: trace REP/REPZ/REPNZ iterations

This allows single-stepping through REP/REPZ/REPNZ iterations. We mainly
need this for a little more realistic timing model when, e.g., copying
large memory areas with REP MOVSB.
Be aware that memory-access tracing only works reliably for REPxx-prefixed
instructions if Bochs was configured with --disable-repeat-speedups, as
this Bochs optimization completely circumvents the usual memory access
paths.
