this can become a problem due to integer division.

any number of ticks less than hz (8000) will be rounded
down to 0 in a number of places now, where as before it
was only less than 100.  i've seen this trip up in the
kernel before, and sometimes that '0' means 'poll', and
sometimes it means 'sleep forever'.

a lot of places in the kernel *do* avoid (eg, with adding
hz-1 and then dividing by hz) but there are a number that
do not...
