Or, rather than invalidating the whole cache, just clear the part you 
changed:

  global $PCache;
  unset $PCache[$pagename];

I ran into the same exact problem with DataQuery, which uses its own 
separate cache array to avoid the need for multiple queries when you do, 
say, a ls command followed immediately by a read command on every record 
that was just listed, as happens when you do a pagelist.  --Ben
