In this situation (a lot of sequential processing), wouldn't it be an 
better approach to start several processes of mkgmap with different tiles?

This could be fully parallelized without dependencies.

Afterwards the different tiles had to be merged into an single img file. 
This process could be started in another extra process with the 
finishing of the first tile.
