"crm stop <resource>" is synchronous: It returns as soon as the 
stop-command has hit the clusters-command-queue :-)
But then it is asynchronous as it returns before the resource is 
actually stopped.

The same applies to "start".

And I think I wish for the gui/cli monitoring tools to also show the 
intermediate states of starting/stopping/migrating...

Thats what you have to do.

Have fun,
