Comment:

 The problem is that the serialization also copies the tag of the structure
 that holds the vector (a srfi-4 vector is a struct with a symbol tag and a
 blob). The type-check compares the structure tag using the equivalent of
 `eq?` which fails, since the evicted symbol tag is not identical to the
 symbol that's used for comparison.

 I can't think of a suitable solution to this right now.
