If htable is used in tdb2 that's a problem.
Tdb and Ldb are LGPLv3 in samba and GPLv2 is incompatible with LGPLv3.
The only way to coherently release Ldb for us would be to release it as
GPLv3 (the only license compatible with both LGPLv3 and GPLv2 (by the
'or any later version' clause) at the same time. But we already have
external programs that depend on a LGPL like license for Ldb.

We need to fix this problem asap.

Do you have a good reason not to ? :-)
