I suspect we are both wrong :-) These structures aren't used in any
hashed structure that I can see, but the effect of the MemSet is to zero
out the it_interval value of the itimer, making sure the timer is a "one
shot" timer - so they are necessary after all, but for a different
reason (it's been a while since I used setitimer, and the man page is
less than a model of clarity).
