I generally try to keep testcases independent so that what is going on is clearer, and changes to earlier testcases don't cascade through the entire set of tests. Look at the testcases for the subversion subrepo support for an example of tests that reuse a repo and wind up being hard to understand. I'd like to avoid that situation for largefiles.

A 2+MB file, given the config in the tests should be sufficient. I keep using 10MiB because it's a "round number" and 10e6 bytes is a boundary that Mercurial cares about.
