John, really, those are scary words in a development situation. 
'maintenance headache.'  Should you not look at a cleaner approach?

Wow, some more scary statements.  '[hopefully] has enough slots' 
Really, you should insure that you have enough.  One of two solutions, 
depending on the problem.

1. unknown number of slots needed - dynamic slot allocation.
2. finite number of slots needed - static slot allocation.
