Slow tests

[Martin Pool]

Thanks, that's cool to get some patches for the slow tests already.

In the hopes of provoking more, here are the slowest classes and the
slowest modules, and the script to get them, with

subunit-ls --no-passthrough --times < timings|python sum-modules.py >
per-module-times

They're pretty similar, indicating that we do indeed have single large
classes for many modules.

It's interesting that bundles are the slowest non-parameterized (?)
tests.  It doesn't seem like something that should be inherently very
slow to test.  transports are probably testing many combinations.
commit builder doesn't seem like it should be the slowest, though
that's partly because it's testing 8 different format combinations.
