 It scales linearly with the number of reading threads.
 
 The tradeoff is that creating a new `IString` is slower.
-A radix tree (compact trie) needs to be traversed to deduplicate the new string,
-a lock needs to be acquired, and the tree needs to be updated if the string wasn't interned yet.

 While the tree walk can be done in parallel from multiple threads, the lock prevents linear

   Currently the crate uses 2x the interned string storage space because of this (1x in storage,
   1x as a clone in the radix tree).
