L{inotify.INotify} emits a C{RuntimeError} when initialized
in an environment that doesn't support inotify as we expect it.
We just try to raise an exception for every possible case in
the for loop in L{inotify.INotify._inotify__init__}.

Test notification from some filesystem operation.
@param mask: The event mask to use when setting up the watch.
@param operation: A function which will be called with the
name of a file in the watched directory and which should
trigger the event.
@param expectedPath: Optionally, the name of the path which is
expected to come back in the notification event; this will
also be passed to C{operation} (primarily useful when the
operation is being done to the directory itself, not a
file in it).
@return: A L{Deferred} which fires successfully when the
expected event has been received or fails otherwise.

L{inotify.INotify} with autoAdd==True for a watched path
generates events for every file or directory already present
in a newly created subdirectory under the watched one.
This tests that we solve a race condition in inotify even though
we may generate duplicate events.
