7    o multi-threading and IO:
8      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
9        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
10      - barrier before and after reading.
11      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
12      - avoid using MDS_WRITELOCAL for LAND pkg output.
13      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
14        common-block variables ; Allows multi-threading with master-thread IO.
15  o change default MAX_NO_THREADS from 32 to 4 ;  o change default MAX_NO_THREADS from 32 to 4 ;
16    and stop cleanly when MAX_NO_THREADS is too small.    and stop cleanly when MAX_NO_THREADS is too small.
17  o add S/R BAR_CHECK to check multi-threaded barrier synchronization  o add S/R BAR_CHECK to check multi-threaded barrier synchronization
