[sage-support] Re: Time limit for computation
If you want to tweak this, it might be helpful to look at the signal
module in python, which is presumably what the above alarm function
uses; a helpful example is at:
http://docs.python.org/lib/node545.html
...and the parent documentation to that has all the details.

Yes, I wrote something to do this a long time ago.
Use the alarm command:
{{{id
alarm(3)
for i in range(10):
print i
sleep(1)
///
0
1
2
Traceback (most recent call last):sleep(1)
File "/Users/was/s/local/lib/python2.5/site-packages/sympy/plotting/",
line 3, in
File "/Users/was/s/local/lib/python2.5/site-packages/sage/misc/misc.py",
line 1345, in __mysig
raise KeyboardInterrupt, "computation timed out because alarm was
set for %s seconds"%__alarm_time
KeyboardInterrupt: computation timed out because alarm was set for 3 seconds
}}}
