Comment:

 I was finally able to re-create this, after Mortsa pinged me about it.

 It seems -r is rather broken, and still tries to read the actual shmlog
 (?) or some combination, instead of the real file...

 This is a mental note for self, more or less, but here's some examples:
 (the foo.vlog gets some data printed to it that matches the size):

 {{{
