No, hardly at all actually, but this patch happens to be right next door
to one of the lines that did change. cstring_to_text() replaces some
grottier stuff that used to be used for the same purpose.
In a few minutes I'm going to verify whether Kris' fix makes the leak go
away for me, and commit to CVS if so.
