Holy cow, I wrote a book!
In a technical discussion, I opened a reply with
Bob's paper which I haven't yet read points out that...
Some people wrote to me to say that the've added this quote to their file
in the hopes of being able to use it themselves someday.
For those who are curious, I found the technical discussion in question.
It had to do with whether the following code is thread-safe:
// initial conditions
int x = 1, y = 0;
int *p = &x;
// Thread 1 executes this
y = 1;
p = &y;
// Thread 2 executes this
Question: Can this code legitimately print 0?
the answer is yes!
