[Mono-list] Possible bug checking existence of file or directory

[Abe Gillespie]

Sorry, expected results - I would have expected an access violation
from the FileSystemWatcher.  But since it's official for .Net to act
like the path doesn't exist, then maybe the FileSystemWatcher is
behaving correctly.

Will all this said, there is one small bug with FileSystemWatcher.
When it throws the message is "Directory does not exists" (notice the
plurality).  I'll file it today.
