JDK-8313212 - G1: Intermittent mark stack overflow during reference processing
Description
During discussion of JDK-8313212 the question came up whether the exponential increase of the mark stack size is "optimal" (wrt to metrics performance, memory usage, code complexity).

In particular it has been suggested that instead of exponential sizing, we should use linear sizing with a configurable amount of increments.

Investigate.
