Description Petr Nejedly 2001-12-07 12:36:03 UTC 
During expansion of folder on Vcs filesystem, lot of time is spent
querying for annotations on filesets.

It is primarily caused by FS lookig up all the DOs for the FOs in the set
where most of the FOs are secondary files of a single DO.

It can be greatly improved by eliminating unimportant FOs at first,
as they are not used in the annotation computation anyway (they are filtered
later).

Moreover, if there will be just one FO left (common case), the DO lookup
can be skipped completly.
