I'm with Antoine here - being able to force a particular seed still
matters for testing purposes. However, the documentation of the option
may need to be updated for 3.3 to emphasise that it should only be
used to reproduce sporadic failures. Using it to work around
applications that can't cope with randomised hashes would be rather
ill-advised.

Cheers,
Nick.
