Do you mean indirectly leak by calling getTime 1K times in an unload handler? 
The page can't do anything that will call this function otherwise, since the
only pointer to it is in the closure.

Re getTime.toString showing different results.  I think this is pretty minor,
especially compared to the problems that this solves (check out the chromium
bug link for comments on how big the problem is, and other drastic changes that
people wanted to do to prevent it).  It won't be possible to do this with no
side effects unless we have V8 changes, which the V8 team doesn't think is
necessary.  They are happy with this approach (Mads reviewed it).

This is a stop-gap measure until we implement <a ping> and evangelize it.
