I am in favor of 1 as well.
@paul-rogers One of the test that fails initially tries to allocate 2GB
(without re-allocation). The test intermittently fails due to Pooled Allocator
not releasing memory back to the system. I don't know if it is supposed to
return memory back to the system when it is closed and whether it is supposed
to be closed at all during the unit tests.
