Follow-up Comment #2, bug #44703 (project octave):
It's the same hardware. I run Linux on the bare metal and Windows XP as a
virtual machine within Linux.
Information on csrss.exe is here
(http://en.wikipedia.org/wiki/Client/Server_Runtime_Subsystem).
It appears that csrss is invoked whenever there are console operations.
During for loops, Octave may be checking the console repeatedly for a 'Ctrl+C'
character which is actually causing the crazy amount of activity I see.
This is another example which shows only 8-18% CPU usage for csrss.exe.
for i = 1:2e3
x = rand (50,50);
endfor
