-/*
-Implements a full reader writer lock, i.e. multiple readers or a single writer.
-
-Below is an implementation using just a mutex for non win32 platforms.
-
-Disable the full reader/writer lock by default. Using the full reader writer lock
-results in better performance when a lot of parallel raycasts are performed but is
-more costly when only a few are performed and slows down serial raycasts.
