I didn't say "restart", I said "lock out the reader for a moment".
Maybe it's easier to grasp if I put it in some pseudo-code:
-- 8< --
Lock_Readers;
I'm not wanting to place locks all over the place when we have cpu locks.
And I didn't want you to take the code literally. Usually someone
encapsulates such specifics. And well, if you can live with a race
condition that might return momentarily bogus counter values every
couple of hours, you may as well leave them out.
On a 32-bit CPU 64-bit reads are not necessarily atomic, so it won't
matter anyway. :P
