See bug 20061 for complete details.

We use an ArrayList to store internal details when writing the registry cache 
file.  Some applications have very large registries.  The ArrayList scheme, is 
therefore, too time consuming.  Some other scheme (hashmap?) needs to be 
considered.

Note that we need to review our data structure list for reading the registry 
cache as well.

Investigate post 2.0.

Have changed the writer to use a HashMap instead of ArrayList.
Re-visit both reading and writing post 2.0

Backed out of change. 
Reverted back to using ArrayList.

Need to review Reader code since ExtensionPoints are always being added to the 
object table and not indexed if they are in a fragment.
