Many thanks for the contribution, I shall look at it shortly.

Unfortunately, I have just discovered another issue which is the static
int nextPriority in GType - this needs to be changed to one instance
per map but at the moment I can't work out what to use as a key to
select the correct value for each map being processed concurrently. If
you have any thoughts on that, please say.

Cheers,

Mark
