I guess that pool exhausting should not be problem with Falcon if SCSI DMA is
not used... So I'm not sure how useful ST_POOL_SIZE tuning is for Falcon.

Anyway TT kernel is using DMA and it might be affected by ST_POOL_SIZE value.
I don't know if it's good safety measurement to leave it to 24 and pull changes
also to NetBSD-4. What do others think ?
