> Assume that the coder meant == 0 what is he trying to enforce. If these 2 bits (_WCLONE and _WALL) are set and your are root then the call is invalid. The bit combination is harmless (setting WALL implies WCLONE [...]), and why would you forbid it for root only.
In May 1998, a caesium-137 source managed to pass through the monitoring equipment in an Acerinox scrap metal reprocessing plant in Los Barrios, Spain. When melted, the caesium-137 caused the release of a radioactive cloud. The Acerinox chimney detectors failed to detect it, but it was eventually detected in France, Italy, Switzerland, Germany and Austria. The radioactive levels measured were up to 1000 times higher than normal.
It is not the only virus. Rabies, also has 100% mortality.
In this case it is the online second hand stores (abebooks, amazon, etc) the ones that are killinh the physical stores.
Correlation != causation. And the author does not ask for caution and research, he asks directly for limits on the technology.
When something bad happens I often find myself going back to Carl Sagan's words on the Pale Blue Dot [0]. Puts everything in perspective, and makes everything feel insignificant, when compared with the vastness of what lies out there.

The virus also stay dormant within your cells, and it is not absolutely clear where, yet. Other viruses which do this (chickenpox, herpes, papillomavirus, ...) are not cleared from the body by the immune system either, but at least the immune system can control them as long as it is healthy enough.
This facts, of course, are no reason to be pessimistic about a cure/vaccine, just explains why it is taking that long. A cure might also pad the way to cure other diseases such as chickenpox and herpes, which may lead to complications later in life.
In the case of set theory I cannot recommend enough Halmos' "Naive set theory". It's completely rigorous yet easy to read, and lays out all the basics of ZF, constructing both ordinals and cardinals.
For probability Khinchin has some very thin fun books, written for some classes he gave in a military school. The books do not get into deep topics but are a good introduction.
For group theory I would try Isaacs' Algebra book. Although the book is one of those books which contain too many topics, he was really enthusiastic of group theory and I have been told the corresponding chapters are very good.
