I had never thought about this before.  But, yeah, that could happen.  I 
don't think there is anything you can do about it though except stay 
with your current client.

What you have to do is stop and ask yourself if your cache is really 
that volatile.  It may be, I don't know.  But, when we started getting 
all flustered about how fresh our cache was, we came to the conclusion 
that the .0001% of the time where we had this problem was not worth the 
brain cycles it would take to fix it.
