If you install a gem (say blah-0.1.gem) several times, the file cache/blah-0.1.gem is only written the first time. AFAIC that's a bug, but I want conformation before fixing it. This needn't affect the 0.8.0 release, anyway. It's a marginal issue, and could be fixed later for 0.8.1 or something. Cheers, Gavin
