Some questions?

1) How many calls did you run through FS to produce this log?
2) What svn rev were you on (line numbers don't match)
3) Best to focus on leaks that are hit on a per-call basis.  init leaks are
annoying but not the end of the world.

Should be looked at -- but I line numbers don't line up with what I have.
