[mkgmap-dev] [PATCH v1] Worker threads stop too early

Attached patch fixes a bug introduced with r115. Bug description: Each worker thread stops when it retrieves the last element for one area. This means that only (max-threads-1) areas are really written until the last element. For the other areas some elements are remaining in the working queues. The patch ensures that a worker thread is finished only if there is no more unfinished area. WanMil
