Summary:                    [patch] missing locking in zt_unregister
Description: 
The following snippet is from the end of zt_unregister:

        if (master == span)
                master = NULL;
        for (x=1;x<ZT_MAX_SPANS;x++) {
                if (spans[x]) {
                        maxspans = x+1;
                        if (!master)
                                master = spans[x];
                }
        }


It gives temporary values tha are invalid to both master and maxspans . 
The values of those variables is used iv various places elsewhere.
