I just pushed my remaining mjw/pending robustness patches to master.
These all should be trivial, mostly simple one-liner sanity checks (see
below for the list). I have tested with most of these this week (and
some were the result of that testing against the afl-fuzzer).

I'll do some more testing on various arches today and will push out a
0.161 release end of the day (Dutch time - UTC+1) unless something
horrible shows up.

And then we can start our work for 0.162!
Lets try to release that in March 2015.

Cheers,
