mod_tile would receive a request, check if a tile is already on disk, if 
it is, deliver it, if it is not, hand over to tirex; tirex would add the 
tile creation request to a queue, and call your engine to produce the 
tile, making sure that to too many requests are executed at once and 
prioritising them nicely (so you could e.g. afford a high priority to 
live requests from users, and a lower priority for background refresh 

The actual creation of the tile would still be done by your code, 
mod_tile and tirex would just make sure that you don't have to bother 
with managing your disk cache, render queues, priorities and all that.
