Look, doing set/test/clear bit on an unsigned long is a very well
established API. We've been doing that _forever_. As I said in my
original email, I have nothing against using bitmaps _where they make
sense_. Manually allocating an array for X number of bits (where X >
32), yes, by all means use the bitmap helpers.
This is my final reply on this topic.
