That is exactly how that shell attack works.
At one point, however, I think that the number of dynamically
allocated task objects should run out, and the program should just
wind about in an infinite loop of erroneous calls to fork(). What a
shame. I'm happy the OS I'm writing does so. It isn't a UNIX-like
one, but the semantics are similar.
