[CDBI] Forced reloads from the DB

Hi all-

Is there a method to only clear the object cache for a single row? I am 
aware of Class::DBI::clear_object_cache but, there are a lot of tables 
that are effectively static, and nuking the cache makes things drag when 
I have to go and reload them all again. I'm having troubles with updates 
on one machine not being propagated to others because of the caching 
mechanism (there are well-defined times when certain objects are 
modified, so ideally, I'd like to use my knowledge of when stuff is 
updated to cause a reload)

thanks in advance-
Andrew
