Xen users - Apr 2005 - xen, tls, futex locks and berkley db

I ran into a problem which I don''t know how to solve.
In order for xen to run in maximum performance, tls should be disabled.
However on that machine I want to run openldap with berkley db backend.
When openldap is started; I get the following error:

bdb_db_open: dbenv_open failed: Function not implemented (38)
slapd[8218]: backend_startup: bi_db_open(0) failed! (38)
slapd[8218]: bdb(dc=eccent,dc=be): DB_ENV->lock_id_free interface
requires an environment configured for the locking subsystem
slapd[8218]: bdb(dc=eccent,dc=be): txn_checkpoint interface requires an
environment configured for the transaction subsystem
slapd[8218]: bdb_db_destroy: txn_checkpoint failed: Invalid argument
(22)

On one mailing list
(https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=152939) I found it
related to :
"This is actually what glibc prints when you try to use futex locks
without tls/nptl libc, iirc."

So enabled tls again, rebooted and tadaaa ... now it works.

How should I solve this? what is the status on tls support? I''m
currently running 2.0-testing. 
Maybe this is not the right place to ask this question, but: can I
compile berkley db (and/or other software) without the need for tls/nptl
support?

Thanx in advance for any pointer in the right direction.

Regards,

Filip Sergeys

What I did to get around this issue, was move our data over to a
postgresql backend. It took a couple of days but it''s now basically
working. If anyone would like help transitioning to a postgresql backend
for openldap, please get in touch off-list and I''d be happy to help.
