Looks like a Gap or Python runaway problem. On Mac OS X, SAGE
doesn't die, but I get this:
=========================================
sage.bin(25351) malloc: *** vm_allocate(size=1069056) failed (error
code=3)
sage.bin(25351) malloc: *** error: can't allocate region
sage.bin(25351) malloc: *** set a breakpoint in szone_error to debug

where the three malloc error messages are repeated an infinite number
of times (i.e., it blew out the scroll-back buffer for this window
(10,000 lines). PID 25351 is 'python' (from sage.bin).
