[strongSwan] Deleting connections

That's exactly what happened.  The problem is that the IKE_SA is checked 
out by one thread and then checked in by another, thus the thread local 
IKE_SA is not reset in the thread that checked it out.
I pushed a patch to master that should fix it (see [1]).

Regards,
Tobias
