Probably Platform, maybe Team. My guess is that it does this check to
accommodate tools that are doing pessimistic locking as the state of
the file may have changed. Have you actually turned off that
preference and seen the flickering go away? My understanding is that
the Subclipse cache management had gotten very fast and efficient. It
is not like we scan all 4000 files.

The decorator code works off a cache and the cache gets told by
Eclipse when something has changed and needs to be refreshed. So not
really sure why you are seeing this.

Maybe you could replicate it with a large public project, like
something in the Apache project repository? If so, then that would
give me and other devs a chance to try to recreate the issue and see
if there are more optimizations to make.
