> There are currently no dtests for the new cdc feature. We should have some, 
> at least to ensure that the cdc files have a lifecycle that makes sense, and 
> make sure that things like a continually cleaning daemon and a lazy daemon 
> have the properties we expect; for this, we don't need to actually process 
> the files, but make sure they fit the characteristics we expect from them. A 
> more complex daemon would need to be written in Java.
> I already hit a problem where if the cdc is over capacity, the cdc properly 
> throws the WTE, but it will not reset after the overflow directory is 
> undersize again. It is supposed to correct the size within 250ms and allow 
> more writes.
