another (IMHO a bit hacky) solution would be to add a userland listener
for open and close. The index server then watch files that have been
opened writeable and do the node-entry mapping by itself.

The problem with open/close notifications is that there would be an awful
lot of them. E.g. Tracker uses the storage kit classes a lot (which
internally all use FDs), so it would probably generate thousands of
notifications when just opening a window with a few hundred entries.


Is it also a problem when watching only the open calls with a writeable flag?
