[mkgmap-dev] Mkgmap appears to hang on some split files

Well, you are probably right in that the Java VM itself in hanging: The 
process hung again and jstack reports: "Unable to open socket file: 
target process not responding or HotSpot VM not loaded".

Forcing it to attach gave an error about HotSpot not being able to find 
a "Symbol". Anyway, I guess it's time to move to another Java VM...
