Subject: c/r, time, and virtualization

Hi,
I wonder what's that status of time namespaces and virtual time(rs) ?
http://lwn.net/Articles/180375/ - "virtual time" coverage in LWN (2006)
http://lkml.org/lkml/2006/4/13/172 - patchset and thread on LKML
http://lwn.net/Articles/249080/ - kernel summit 2007 - containers
It will be handy for c/r of timers (posix-timers) that I'm working on.
A couple of obstacles off the top of my head:
- Lack of clone flags -- we can use clone_with_pids() for that.
- Fast gettimeofday() via vdso -- perhaps a vdso page per time-ns
(containing the necessary deltas).
Is anyone working on it ?
Oren.
