System variables:
----------------
Solaris 2.6:  Displaying/modifying system variables (such as may appear
              in /etc/system).
              To display:
                  > echo "shminfo_shmmax/U" | adb -k /dev/ksyms /dev/mem

              To set (example from rich.pppl.gov file /etc/system):
                  * increase limits of select ipcs parameters
                  set shmsys:shminfo_shmmax = 41943040
                  set shmsys:shminfo_shmseg = 10
                  set semsys:seminfo_semmap = 20
                  set semsys:seminfo_semmni = 20

malloc:
------
Solaris 2.6:  specify "-lmalloc" library.  This is the Gnu "malloc".
              Regular malloc can blow up, it seems (see ~gibney/ida3/src
              Makefile for "test", from ida3mds_routines.c)

              Google/Yahoo search "malloc solaris realfree" shows that
              this bug has been reported numerous times (even pre-1998),
              but no patch yet ...
