Simon King mentioned that sometimes his code crashes/leaks/etc. So make
it so one can do:
{{{
@fork
def f(x,y,z,...):
...
}}}
and then f gets computed in a blocking forked process, and the result is
returned via pickling. This is 100% to thwart mem leaks, segfaults, and
guaranteed timeout possibility. This could be basically just a light
wrapper around @parallel(1). Also, make a global flag to turn this off,
so @fork does nothing.
