I changed the locking in V1.3.  The two calls are now:
   old_value = lock();
   .
   .
   .
   restore(old_value)

These nest properly and you can build critical sections more easily.

I am leaving for a month today.  I may get a chance to see news around the
beginning of August, but I won't be reading my mail until Aug 24.  I hope
no other postings have been garbled.  Maybe I will mail Vincent Broman
all the postings so he can verify them against the archive.
