Description Isao Yanagimachi 2003-02-26 15:16:14 UTC 
vcscore calls the VcsFileSystem.setVirtualDataLoader() per 
every file. VcsFileSystem.setVirtualDataLoader()  in turn 
calls DataLoaderPool.setPreferredLoader(). 
DataLoaderPool.setPreferredLoader() is not efficient in 
that it refreshes parent folder. So if there are 1000
files, there will be 1000 parent folder refreshes. 

This really slows down the performance of generic VCS 
profilers especially the CMS generic VCS profiler pluggin 
from OpenVMS since it is not uncommon for CMS to hold 
thousands of files in a directory.
