ldconfig slow on HEAD?

[Nikolai Lifanov]

Hello!

For the last couple of weeks or so (I can't nail the exact revision
because I didn't think much of it then), ldconfig from /compat/linux
(linux_base-c6) has been very, very slow. It sits there consuming 100%
of one CPU core for a few minutes. This is severe when
installing/uninstalling several linux_* packages.

My system is otherwise idle.
Let me know if I can provide better diagnostic information.
