I am trying to use the @fork decorator as described here:
http://www.sagemath.org/doc/reference/parallel/sage/parallel/decorate.html
in order to force a function not to take more run time than some
maximum. The examples on that page all work but this does not. Why
not?
sage: @fork(timeout=10, verbose=True)
....: def timedgens(E):
....: return E.gens(descent_second_limit=10)
....:
sage: for E in cremona_curves([35..45]): print E.ainvs(), timedgens(E)
(0, 1, 1, 9, 1) []
(0, 1, 1, -131, -650) []
(0, 1, 1, -1, 0) []
(0, 0, 0, 0, 1) []

IndexError Traceback (most recent call last)
All goes well until the return value is a non-empty list, when this
IndexError is triggered. What on earth is going on?
