I'm missing something. If the crash was due to the JVM unconditionally creating stacks of 2*PAGESIZE, then wouldn't the default (smaller) page size make the problem worse? (I doubt a JVM would work well with 8Kb or 16Kb thread stacks!)

Or were they doing something like

if (PAGESIZE > 16384)
... size stack to 2*PAGESIZE ...
else
... size it to something sane ...

If so, well, *ick*.
