Having said that there is a related topic that you might be able to assist

"The TCP/IP Out-of-band character with Java->SSL->Stunnel."
I know Java can't receive OOB data (except inline) but it can send them and
SSLSocket inherits sendUrgentData() so it's vaguely on topic. The problem I
foresee according to the STUNNEL docs is that unless the OOB character is
in-lined then it will just be ignored. Can anyone confirm this?
SSLv3 seems to mandate that the OOB data be supported (as normal data with a
complete SSL wrapper record) but I can't find anything in the OpenSSL
routines that modify (or inform) an SSL_Read() that it's got the OOB; can
anyone confirm this?
At first glance, I just can't see a problem with STUNNEL/OpenSSL unpacking
the OOB byte and passing it on to the in-the-clear connection (with the
option for *both* inline or OOB) but maybe that's just me?
I would go for a simpler solution.
Either open a second socket connection for this traffic or make
a protocol on the original socket that has both "next data block"
and "urgent interrupt" messages.
