Is there any user API to disable the dependency manager (atleast during 
debugging and development)?

What is the basic structure of the dependency management search 
algorithm?  Is it something like:

- For every part of an interface exposed
    - For each item used in the interface
        - Look up the item and make sure that is exposed

If it is something like this, then that could definitely be biting me.  
I have a *huge* number of symbols and something O(N^2) like this could 
really consume a lot of time.

In the meantime, I am trying to collect some profiler information to 
find out exactly where the time is being spent.  Once I have those 
numbers collected I will pass them along in case there is anything that 
can be done to increase performance.
