window of the view into the application thread. This solves the race condition with asynchronous SetViewCursor and deleting the cursor immediately afterwards for real. * The ServerApp now requires a reference to the current cursor, just in case... * Added TODOs for caching the BView token, it's currently resolved for every single BView call that talks to the server... not good! git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31133 a95241bf-73f2-0310-859d-f6bbb57e9c96
