This is a bug to address part 2 of bug 313953. Thomas, sorry I missed your questions in the original bug. Yes, there are almost 6000 files on disk which have been removed.

- copy test data (3000 features, 3000 plugins) to dropins folder
- start Eclipse
- shutdown
- delete all plugins and features except 1 of each
- start Eclipse
- this start takes almost 10min. 

Here is the query that we are performing:

// create a query that will identify all ius related to removed files.
// It's safe to compare a String with a File since the auto coercion will
// first convert the String into a File.
IQuery<IInstallableUnit> removeQuery = QueryUtil.createMatchQuery( //
	"$1.exists(x | properties[$0] == x)", FILE_NAME, removedFiles); //$NON-NLS-1$
IQueryResult<IInstallableUnit> toRemove = metadataRepository.query(removeQuery, null);
metadataRepository.removeInstallableUnits(toRemove.toUnmodifiableSet());

Thomas, is there a way we could re-write the query or do something differently here?
