[...] Your patch looks useful in its own right, but GNOME, Firefox, Mozilla and XMMS have not crashed once for me since I fixed context restoring in libpthread on amd64.

I would be interested in hearing whether you still have problems with libpthread and GNOME after updating your system, both with and without nss_ldap. Tim
