Backporting an AsyncGetCallTrace patch to OpenJDK6

[Paul Hohensee]

The most stable version will vary.  We'd like the openjdk version to be 
product-ready,
but we haven't been able to do that yet.  For now the most stable 
version is 6-open,
which is hotspot 10 plus fixes.  When 6u10 ships, our plan is to push 
the vm that
comes with it (hotspot 11) into 6-open.
