[lxc-devel] Working with glibc (PID/TID caches).

[Carlos O'Donell]

There was a complaint a while back from someone working
on containers about glibc PID caching. I recently received
another request to provide userspace with a way to reset
any PID or TID caches to make clone-based sandboxing easier
(CLONE_NEWPID).

How did lxc workaround the PID cache in glibc? What APIs
could glibc provide to help the implementation of containers?

Cheers,
Carlos.
