[mkgmap-dev] mkgmap and threads

Sat Nov 20 22:26:39 GMT 2010

I have observed that typically mkgmap does not use more that 2 threads. 
If the max-jobs parameter is set to a greater value than 2 the surplus 
threads are blocked in the MapMaker.loadFromFile.

There is a note in the MapMaker source code:
		// work around non-reentrancy of GType priority stuff
		// by serialising the map reading

Is there any chance to remove this synchronization to get a gain of more 
threads? What has to be done to remove the synchronization in the 
MapMaker class?
