[gdal-dev] Gdal Asynchronous IO

In Rfc 24: GDAL Progressive Data Support it says that the metadata for a 
driver will specify metadata item "DCAP_ASYNCIO" as yes if the driver 
supports asynchronous IO. So, code like this should retrieve this option:
const char* s_asyncio = drv->GetMetadataItem("DCAP_ASYNCIO");
However, I have been unable to find any drivers that return "Yes".

So, is this the correct way to check whether a driver supports 
asynchronous io?
Are there any drivers that currently support this besides Kadaku which I 
don't have?
