[PATCH] nsswitch extensions + caching

Hello!
I've made the "nsswitch + caching daemon" project during the Google's 
Summer of Code. I'm still working on it - there is always a room for 
improvements :)

Since previous release, I've made a lot of changes to the initial 
version, fixed some bugs, and this version seems to be worth using it :)

Here is the the new release of the patch:
http://www.rsu.ru/~bushman/nsswitch_cached/nss_cached_rev2.patch

The description of the project itself and of its several new features 
can be found here:

Your feedback would be great!
