def remove(fd, wd):
    # When inotify_rm_watch returns -1 there's an error:
    # The errno for this call can be either one of the following:
    #  EBADF: fd is not a valid file descriptor.
    #  EINVAL: The watch descriptor wd is not valid; or fd is
    #          not an inotify file descriptor.
    #
    # if we can't access the errno here we cannot even raise
    # an exception and we need to ignore the problem, one of
    # the most common cases is when you remove a directory from
    # the filesystem and that directory is observed. When inotify
    # tries to call inotify_rm_watch with a non existing directory
    # either of the 2 errors might come up because the files inside
    # it might have events generated way before they were handled.
    # Unfortunately only ctypes in Python 2.6 supports accessing errno:
    #  http://bugs.python.org/issue1798 and in order to solve
    # the problem for previous versions we need to introduce
    # code that is quite complex:
    #  http://stackoverflow.com/questions/661017/access-to-errno-from-python
    #
    # See #4310 for future resolution of this issue.
