The third operation\r\n        needs a lock only when two or more threads will be inserting objects into the list. The fourth\r\n        operation requires a lock only when one thread will add an object while another thread removes\r\n        the object and the incoming count is not yet zero.\r\n          Having a lock associated with a SubMtxList object is optional, for example, it is not needed\r\n        during a serial factorization nor a MPI solve. In the latter case there is one SubMtxList per process.\r\n                              1\r\n-              2                          SubMtxList : DRAFT August 3, 2025\r\n+              2                           SubMtxList : DRAFT July 1, 2024\r\n               For a multithreaded solve there is one SubMtxList object that is shared by all threads. The mutual\r\n               exclusion lock that is (optionally) embedded in the SubMtxList object is a Lock object from this\r\n               library. It is inside the Lock object that we have a mutual exclusion lock. Presently we support the\r\n               Solaris and POSIX thread packages. Porting the multithreaded codes to another platform should\r\n               be simple if the POSIX thread package is present. Another type of thread package will require\r\n               some modi\ufb01cations to the Lock object, but none to the SubMtxList objects.\r\n               1.1   Data Structure\r\n@@ -52,15 +52,15 @@\n                 1.
