Comment(by Sebastian):

 Trying this on a Windows 7, unfortunately I'm getting "Permission denied"
 when we're trying to non-blockingly lock a file we have locked before, and
 a "Resource deadlock avoided" error when trying to lock a file we've
 already locked blockingly (the errors are the same when some other process
 has the files locked); so it does unfortunately look like simply replacing
 EDEADLOCK with EACCES won't do. My next-best approach would be to say that
 if either EACCES or EDEADLOCK is returned we use the error case.
