Breaking invalid sessions is more complex than people might think.
Validating sessions would also involve performing OCSP request, checking 
whether the local certificate was revoked by remote site, etc.

I think the only reasonable way to implement it would be to execute 
SSL_renegotiate() for each SSL structure, so it renegotiates encryption on 
next data transfer.  stunnel does not even keep a list of all SSL structures, 
now.  Would you like to sponsor this feature?
