Gitit uses filestore, and filestore aims at multiple backends. For
example, what's the timestamp for files - when the backend is sqlite3?
Perhaps there *is* some way to query sqlite3 as to the last date a
'file' was modified. But then there are other issues; for example,
filestore only lets you see recorded files and changes. If I cd into
my wiki directory, and rm -rf everything except _darcs, but I don't do
any darcs record, Gitit chugs on blissfully unaware - it's always
doing 'darcs query contents file', not 'cat file'. But if it was
calling ls on each page read, then caching will be messed up (at the
least).
