I feel like I should write a webkit-patch command to do this.

Looks like <http://build.webkit.org/builders/SnowLeopard%20Intel%20Leaks/builds/15164>
was (relatively) clean.  Starting at
<http://build.webkit.org/builders/SnowLeopard%20Intel%20Leaks/builds/15165>,
there's a fog of tons of crashes.  When we finally emerge from the fog
at <http://build.webkit.org/builders/SnowLeopard%20Intel%20Leaks/builds/15220>,
we have 14437 leaks.

So, that's a regression range of 79781--79968.  :-(
