In reply to: NPTL Support?
Parent article: OLS: Xen and UML
As the parent says, Xen runs NPTL code OK - but a bit slower than other code. Apparently there is a patch to glibc for Xen guests that can improve the performance.
UML does not support NPTL right now. You typically need to just mv /lib/tls /lib/tls.broken to prevent apps using it. There is talk on the mailing lists of some modifications so that it will support NPTL in the future.
The main limitation that this all seems to create is with db4 which depends on NPTL for interprocess locking. e.g. this can affect subversion users, and the workaround is to use a file system backed repository instead.
