Hi Robert,

Could peeps do svn update and test things and let me know how you get on.
Here are my observations on OS X:
osgcamera -s -2 cow.osg
works as expected now -- after closing the last window, the app terminates
osgcamera -d -2 cow.osg
same problem as reported previously: osg::OperationsThread::cancel()
called from the main-thread is waiting, and the other threads are
waiting inside a mutex.lock() called from :
#2 0x000b4db9 in OpenThreads::Mutex::lock at PThreadMutex.c++:122

osgcamera -g -2 cow.osg
seme problem as -d, after closing one window the app is locked:

osgcamera -c cow.osg:
