* Fixup uses of `sanity`
* Remove unnecessary comments.
These checks are better explained by earlier comments about
the context of the test. Per @tgross, moved the tests together
to better reinforce the overall shared context.
* Update nomad/fsm_test.go
Handle stalled readers (e.g. network write got stalled), by having
escaping io have a buffer so it looks for escaped characters in the
stream.
This simplifies the implementation considerably, as we can look
for new lines followed by escaped characters directly.
Also, we add a test to ensure that any partial results are flushed to
readers.
