wmIsRunning bit in the server

How can I query from within the server if a WM is running on the  
server?  I have a thread on the server that needs to wait until  
xinitrc has "finished" (ie, the window-manager is running) before it  
should continue.  I know that if you try to run a second WM on a  
server with one already, it will fail, so this leads me to believe  
that there are bits in the server itself which I can query to figure  
this out.  I grepped a bit looking for something but couldn't find  
it.  Could someone point me in the right direction?
