If this RFE pans out in practice, it might make 6329603 moot.
As noted in 6541037, ergonomic adaptation of perm gen collection may
be tricky because of the more bursty nature of allocation therein,
which might generally defeat predictive models based on smoother
statistics. Nevertheless, it would be an improvement over the
current state of affairs in the case of non-terminating
applications that do not have a bound on their perm gen
allocation volume.
