Hrm.  It used to be possible to track things down by looking at the historical results at <http://build.webkit.org/results/SnowLeopard%20Intel%20Leaks/>, but we don't appear to keep the results for very long any more.   It would be possible to build and bisect locally to track down when they were introduced.  However, given the sheer volume of leaks I suspect it would be relatively easy for someone familiar with whatever code is leaking most prominently to track down the leak.

I don't recall whether this is possible.
