The HZ constant started out as a locale-dependent variable, and could be 
either 50 or 60. The purpose and history of this is in a kernel howto 
somewhere. Perhaps in the kernel-developer's howto.

It does relate to some critical timing, if I recall correctly.

It's been a long time since I read the kernel how-to's (since 0.99?) and 
they could explain much better than I ever could.
