The following code does not work as intended (I imagine), i.e. it does not
interrupt the computation after 3 seconds.
{{{
#!python
#!/usr/bin/python -tt
from sage.all import *
import time
def main():
alarm(3)
try:
EllipticCurve([123456, 789011]).rank()
#time.sleep(5) #code works as intended if the above command is
replaced with this
except KeyboardInterrupt:
print 'Took too long'
# This is the standard boilerplate that calls the main() function.
if __name__ == '__main__':
main()
}}}
