At the risk of stating the obvious - couldn't we just wait one second
before generating the preview?  This seems to be by far the easiest
solution, and I don't think anyone really cares if they have to wait a
second for the preview.  You could even check what the system time is
and then just sleep for the remainder of the second, which would be
500ms on average.
This seems to be a far more practical solution, no?
