Valentin Rothberg e72d18e1d7 lockfile test: make concurrent RW test determinisitc 
Inspired by the stdlib's rwmutex tests, we are using counter and
different valid ranges for reader and writers.  Also use a channel to
synchronize on Goroutine completion.

Make the cocurrent read tests deterministic by synchronizing the
gouroutines with three channels.  The code is inspired by the
stdlib's rwmutex tests.

Nalin Dahyabhai aa5c9b7871 lockfile: add some unit tests 
These aren't exhaustive, but they're something.

Also change Modified() to not return an ENOSPC error when the length of
the last-writer ID doesn't match the one we'd use, since it's enough
that it's different from the one we'd use, whatever its length.
