Actually, I found the issue.  I will try to explain it as follows:

Assume that I have data that needs to be hashed by 4 different keys
(key1, key2, key3, key4).  If there are situations where key3 and key4
are non unique and I make them the same value for every entry, when I
remove an entry from my table that has a lot of entries (ex. 10000), it
may take seconds to for the removal to take place.

Is there a way to improve on this?  Something like be able to tell the
multiindex to not always hash a key if the value is not set (example, if
integer, value of -1 means not set)?

Thanks for any help.

That depends on your compiler and build system.
