Getting thread-local mem..

[Keith McGuigan]

If you need the memory to stay alive only within a particular function scope 
(even a high-level one), you can use resource memory, which is thread-specific 
and is automatically cleaned up by a ResourceMark.  It is not global memory, 
though - it will be reclaimed when the ResourceMark destructor is called.  But 
if you put it at a high enough level maybe this will do what you need?

Take a look at allocation.hpp for info on this and other possibilities (for 
example if you are going to allocate out of C-heap, there are routines in there 
for doing that too).
