This data object is returned by GeomVertexArrayData::get_handle() or modify_handle().
As long as it exists, the data is locked; when the last of these destructs, the data is unlocked.
Only one thread at a time may lock the data; other threads attempting to lock the data will block. A given thread may simultaneously lock the data multiple times.
This class serves in lieu of a pair of GeomVertexArrayDataPipelineReader and GeomVertexArrayDataPipelineWriter classes
