Summary: another CANCEL bug

Initial Comment:
Hi!

I have found another CANCEL bug.

$ /usr/sbin/openser -V
version: openser 1.2.0-dev12-tls (i386/linux)

I think the problem occours when one branch answers 200 OK before the other branches send a provisional response. Then, this other branches do not get canceled. See dump below:

Hi Klaus,

If I recall correctly, theis problem was debated several times ago. It is
more a logical issues than a bug and was labeled as "delayed CANCEL" - as
the trace shows, it is about a transaction with a non-responsive branch,
transaction wthat gets completed. After that a reply from the
non-responsive branch arrives. The questions is what should you do?? If the
transaction is still in memory, you can generate a delayed
CANCEL.....otherwise the reply will not match any transaction and it will
be stateless fwd....Any thoughts???

regards,
bogdan
