I looked through bugzilla and the archives but didn't find anything
relevant.  I will look harder...

Would you accept a patch that resolved symlinks in the path after
failing to find a suitable thumbnail with the original? I'd think hard
or symbolically linking the equivalent thumbnails might also be
reasonable to avoid the second check in the future.

Yeah, I knew it entailed reading the entire file, just figured it would
be faster anyway, but after a few 'time'd runs locally, this won't work.
Well, it'll work, but it doesn't buy anything.

I'm almost tempted to suggest an inode/device cache of some sort for
local files.  That might also solve a number of issues with removable
devices as well...
