 verifier: serialize the fetching of blocks within a share so that we don't
 use too much RAM

 Shares are still verified in parallel, but within a share, don't request a
 block until the previous block has been verified and the memory we used to
 hold
 it has been freed up.

 Patch originally due to Brian. This version has a mockery-patchery-style
 test
 which is "low tech" (it implements the patching inline in the test code
 instead
 of using an extension of the mock.patch() function from the mock library)
 and
 which unpatches in case of exception.

 fixes #1395
