*SUMMARY
WebKit r31147 <http://trac.webkit.org/changeset/31147> replaced a "compact"
hash with a perfect hash for storing properties of built-in DOM objects. 
Unfortunately, this tends to use more memory to store rather small amounts of
data.  It would be nice to restore the original "compact" hash code and to
provide a build-time choice to select the hashing algorithm.

* NOTES
<rdar://problem/6331749>
