 This PR contains even less information that your non-PR email, but what 
 you're describing sounds like intended behaviour.  Specifically, 
 creating a snapshot causes all other filesystem access to pause until 
 the creation is complete, which can take a long time on large or active 
 filesystems.
 
 Can you please confirm that if you wait long enough the operation completes?
