Thanks for giving this a look.

I'll update that so it's more clear.
But, just to clarify here first, the 1GB restriction is just in
regards to the maxBlockSize parameter when creating a context.
Anything over set->allocChunkLimit goes on a dedicated block and there
is no 1GB size restriction on those dedicated blocks.
