Or a configuration option, rather than a magic number.  Or add a LRU- 
flag to the alias table, and pre-load a subset of the aliases that  
are most recently used.  You'll probably end up with a hit rate of at  
least 80%.  You wouldn't need a magic number or a configuration setting.

Another improvement might be to stop executing SQL queries at the  
point where all aliases are known to be in the local alias cache.  It  
wouldn't make a difference for sites with many aliases, but for small  
sites that only alias their primary links, it might make a big  
difference.

Patches? :)
