At least for IMAP folders this is documented:

[cache_folders]
If set to true, note that any folders created on the server during an  
IMP session that are NOT created via IMP will not be displayed until  
the next login. If IMP will be the exclusive means of accessing the  
mail server, or you are not concerned about this behavior, this  
setting should be set to true.

But for message status, delete, new etc. it's working fine here with  
Cyrus as IMAP server and parallel access with Thunderbird (IMAP) and  
IMP/Horde. You have to wait for refresh for sure but this is standard  
IMAP behavior.

Not sure maybe you should explain in more detail what is failing and  
what your test-cases are.
