** as of 02/2022, Jules has made progress fixing up the property tree implementation to become thread safe, which might make it more feasible to move some parsing/SGPropertyNode processing into a worker thread using a private property tree. | ** as of 02/2022, Jules has made progress fixing up the property tree implementation to become thread safe, which might make it more feasible to move some parsing/SGPropertyNode processing into a worker thread using a private property tree. | ||
