 How do you count memory usage? At least under Linux it's quite not
trivial. In particular I'd be highly surprised if these 30MB were all
unshared.

 There is an extra/missing 0 or two somewhere, 30MB*500 is more like 15GB.

 And, of course, if you actually need 20 shared MB per user and 10 MB per
instance it becomes "only" 5GB.

 It should be but I honestly don't think you're going to gain much except
the possibility of having many new and exciting bugs by doing it. Using
multiple threads doesn't magically reduce the memory consumption, although
it can reduce the numbers shown by ps.
