static void makVrv::DtIndirectGeometry::initializeDtDeKeyedInstances ( DtDe & de )

static

DtIndirectGeometry has a bunch of components that are references (creators, higher level managers, etc) These are keyed on DtDe and hence call ::instance of those. These implementations are not thread safe. They call findInstance and then registerInstance (if instance was not found) with no higher up locking guarding both functions. When a bunch of DtIndirectGeometries are made from multiple threads, the call to ::instance to any one of these can cause thread safety issues. So, call this function, once from outside (e.g. DtOsgRenderer::postInitialize), so all these are initialized properly and subsequent calls inside ::instance always hit only DtDe.findInstance and return the pointer in question. This was found recently in cdb for a particular database. It's only happenstance that we did not run into this before.
