I'm trying to wrap inotify functionality for python. I ran into a problem.
In order to use python's select on the fd, I need to use python's
os.fdopen. It seems os.fdopen calls:
fcntl(4, F_GETFL) = -1 EBADF (Bad file descriptor)
Looks like inotify doesn't support calling fcntl. Should it?

F_GETFL is implemented in the VFS, and it can only fail if the fd does not
denote a valid file handle.
