My poor old Sun is suffering a very high load average after running

Total: 141 processes, 334 lwps, load averages: 10.50, 9.78, 9.34
With two processors, the top 10 processes are only using about 50% of
the CPU time, but the load average is huge.
I downloaded the DTrace toolkit for Solaris, and run the program and see
below all these processes being created. Thousands of them in very quick
succession. This is what's grinding my system to a halt. See below
(there is some more text below this.)

Something in Sage is getting into a mess calling grep and top in quick
succession. Is this supposed to be the performance monitoring tool? If
so, calling 'top' is not a good idea. It is not a standard tool, and
well known to be inaccurate on Solaris.
