Cran task views seems to be a "once-per-session" process -- the first attempt to access views in a (RGui for Windows) session works, but subsequent attempts fail. There is a noticeably long pause before the failing call returns.
Example session with two calls to "available.views" follows, but similar effects have been observed with two calls to "install.views" and even a call to "available.views" followed by a call to "install.views".
