    Attachment: MapWritableCopyConstructor.patch

Attached patch add a copy constructor to  the map writable and use it in the 
CrawlDatum.set methode. However there are more methods in the code where meta 
data are passed from one CrawlDatum to a other, but I don't can see any risk of 
concurent usage of the mapWritable there. 


> CrawlDatum.set just reference a mapWritable of a other object but not copy it.

> Using CrawlDatum.set(aOtherCrawlDatum) copies the data from one CrawlDatum to 
> a other. 
> Also a reference of the MapWritable is passed. Means both project share the 
> same mapWritable and its content. 
> This causes problems with concurent manipulate mapWritables and its key-value 
> tuples.
