I will test that, but as long as distros do not patch their glibc, too,
we are in the same sitiuation as i am with my db4-hack: i have to
rebuild a central package which is tricky to compile. I have to do that
each time the package is updated. Apt/yum shall not update it to newly
released versions (only from my own repository, resp.), so i have to lie
about the version number or i have to rename it (db4 ==> db4-xen). Try
to replace db4-4.2.52 with db4-xen-4.2.52 on a running system ... that's
really UGLY.

Does anybody know if & how RedHat solved that problem on FC4test1 (which
is shipping with xen-unstable & cyrus-imapd)?
