Yes.

[.Last.lib is called when a package with a namespace is detached.]
Indeed, but see `Writing R Extensions', under `Load hooks', and
Various @R{} functions in a package can be used to initialize and clean
up. For packages without a name space, these are @code{.First.lib} and
@code{.Last.lib}. (For packages with a name space, @xref{Load hooks}.)
I'll update library.Rd to mention this and user hooks.
