I took a stab at doing that. Attached, untar in the top source tree, and
do "cd src/test/isolation; make check". It's like "installcheck", so it
needs a postgres server to be running. Also available in my git
repository at git://git.postgresql.org/git/users/heikki/postgres.git,
branch "serializable".

I think this will work. This is a rough first version, but it already
works. We can extend the test framework later if we need more features,
but I believe this is enough for all the existing tests.
