winbindd has undergone a lot of work since 3.0.23d was
released. In fact a partially re-written winbindd will
be one of the main advertized features for 3.0.24. If
you're willing to test the current code in the SAMBA_3_0_24
svn branch I'd really appreciate it, as I'm not aware
of any current memory leaks in the new code (but it does
need wider testing).
