+// 1)  VERIFY(), via DEBUG_ASSERT, from Brent Verner <brent@rcfile.org>.
+//   This file is included in the various testsuite programs to provide
+//   #define(able) assert() behavior for debugging/testing. It may be
+//   a suitable location for other furry woodland creatures as well.
+//
+// 2)  __set_testsuite_memlimit()
+//   __set_testsuite_memlimit() uses setrlimit() to restrict dynamic memory
+//   allocation.  We provide a default memory limit if none is passed by the
+//   calling application.  The argument to __set_testsuite_memlimit() is the
+//   limit in megabytes (a floating-point number).  If NO_MEM_LIMITS is
+//   #defined before including this header, then no limiting is attempted.
