Comment:
Well, I've tested it on Intel Mac as well and I get different errors but
interrupting still seems to work. It's nontrivial to find things that I
can interrupt fast enough!
There was one weird thing that happened when I repeatedly interrupted
and/or let finish the computation
{{{
sage: y = function('y', x)
sage:
desolve(sqrt(y)*diff(y,x)+e^(y)+cos(x)-sin(x+y)==0,y,contrib_ode=True)
}}}
from the documentation. This is ''not'' tested, because it just raises an
error (Maxima can't solve it), but in one session I was able to really
confuse ECL and kept getting an unbound INFLAG error. But then I tried to
get this again in the next session and, try as I might, I couldn't get it.
So I think this is at least as robust as our previous one. Or one could
compromise with three interrupts and not infinitely many :)
So let's say positive review.

Incidentally, you might find this amusing.
{{{
sage: maxima.eval('factorial(100000)')
'282422940796034787429342157802453551847749492609122485057891808654297...
sage: maxima.eval('factorial(100001)')
'100001!'
}}}
