This is a fix for a test that we don't really even need. We are attempting
to verify that we can allocate a single value vector of 2 GB by doubling from a
small amount. On the last allocation, we have a 1 GB vector doubling to 2 GB,
so we temporarily need 3 GB.
But, vectors should never get this large. The batch size limitation project
is doing work to limit vectors to the 16 MB Netty slab size.
For this reason, this is a workaround to a test for a feature that is
actually a bug which we will be fixing in a later release.
