Of course you're right, such, whether it be a background worker process 
through FPM or other FastCGI-like implementation, or a separate daemon 
picking up on tasks in a queue, or whatnot, would enable a client to 
simply HEAD-and-ignore.

Additionally, message bus capabilities for Cyrus IMAP Andreas Osowski 
is working on merging back into upstream master would allow many more 
components to do many more things completely autonomously, where many is 
"infinite" in that it is limited to message-bus' scalability.
