Each Apache process has its own Python interpreter, and in a
default Apache install each process only handles 50 or 100
requests before exiting.  Which process you get for a particular
page load depends on the OS scheduler and the exact timing, but
on an unloaded machine you can easily hit the same one 10 or more
times in a row.

But in general, you can't keep server-side shared data this way.
