Test 042 creates files with a lot of extents, but we don't have
coverage of extent countsin the hundreds of thousands or greater.
I can put together a simple test to do it using preallocation and/or
hole punching, though I'm not sure what the runtime will be.
Given we assume we have at least 10GB on the scratch device, I can
easily create a couple of million extent files on a 4k block size
filesystem for repair/db to walk....
Cheers,
Dave.
