Note that the original paper doesn't say anything about crashing. Their point is that E.Coli regulatory network has a different topology than Linux call graph, in particular, a much lower overlap between modules and little reuse of low-level workhorses. They postulate that higher level eukaryotic networks would have more reuse and be more similar to Linux call-graph. http://www.pnas.org/content/early/2010/04/28/0914771107.full.pdf+html http://www.pnas.org/content/early/2010/04/28/0914771107.full...
