[Announce] Fault injection in upcoming strace 4.15

This summer, as a part of his GSoC 2016 project, Nahim El Atmani has implemented[1] a prototype of syscall fault injection. Fault injection is a testing/debugging technique which tampers the system calls made by a program in order to check (correctness of) program's behaviour in presence of
