The answer is, "it depends" :)

For most things I do I keep only about a 5 minute cache, so its usually not 
too critical to force it to expire.  For the cases it is I either have the 
CMS do a PURGE, or allow PURGEs to happen from specific clients (either via 
a http PURGE command or SHIFT+RELOAD).

That's just me though probably.
