Why is this change needed to fix the memory leak?

[James Hawkins, 2012/06/01 23:53:13]

Didn't say it was.  It's drive-by cleanup I saw while fixing this issue.

OK, the CL description did not mention it included other drive by cleanup, so it
was not clear it was that.  Maybe update the CL description?
