Michael,
On 10.4.x for i386 there is a slightly different debug mechanism for the
socket lock and unlock. Instead of reserved3 and reserverd4, there is
circular buffers with the 4 last lock/unlocks for the socket:
u_int32_t lock_lr[4];
int next_lock_lr;
u_int32_t unlock_lr[4];
int next_unlock_lr;
"next_lock_lr" and "next_unlock_lr" provide the number (0 to 3) for the next
debug link register slot to be used. You can work your way from n-1 and find
the last four lock/unlock recorded for that socket.
