Re: troubles with caps

I think it's fairly important for libc to do some caching locally.
While it is true that programs like ls use auxillary caching procedures
such as user_from_uid(), I do not consider this desireable because
such auxillary caching mechanisms are not tied into the invalidation
mechanism that CAPS has (and in the future the invalidation mechanism
may be up-call based). Tight integration is needed for the caching
to work properly.
