Hmm.  Could you be more specific about the nature of the problem you're seeing 
here?  UMA shouldn't impose any default zone limit on the file_zone if none is 
set.  Are you sure it's the struct file zonelimit you're running into, and 
not, say, the socket zone limit, etc?

Also, don't use SI_SUB_EVENTHANDLER+1 -- add a new event type, perhaps
