So I ask you, if there are any experiences
with that. In special I ask myself, how the removal of the TLS libraries might
affect performance and stability of those applications.

I tried using Oracle 10g on a rather old version of Xen from bk (it
still uses kernel 2.6.9) with Lineox 4.
TLS libs (/lib/tls, /usr/lib/tls, /usr/X11r6/lib/tls) moved out of the way.
This configuration works great running MTA (mail filtering purposes) and
web server (LAMP).
However it didn't work quite as expected running Oracle.
Oracle runs, but often I would get entries like these on alert log :
ORA-07445: exception encountered: core dump [kkogbro()+2832] [SIGSEGV]

ORA-00600: internal error code, arguments: [kghssgai2], [1], [36], [],

and sometimes it just dies.
Revert back to native linux, everything works fine.
I haven't had time to test current Xen 2.0.6 (or nightly snapshot) though.
