[erlang-questions] now() on SMP

[Tony Rogvall]

I have verified the bug!

The following code crash (sometimes) with badarg on my Mac Dou Core  
2: (+S 10 -smp )

(catch ets:delete(t)), ets:new(t, [public,named_table]), lists:foreach 
(fun(I) -> spawn(fun() -> lists:foreach(fun(_) -> N=now(),  
true=ets:insert_new(t, {N}) end, lists:seq(1,100000)) end) end,   
lists:seq(1, 5)).

=ERROR REPORT==== 27-Jun-2007::13:14:33 ===
Error in process <0.2192.0> with exit value: {badarg,[{ets,insert_new, 
[t,{{1182,942873,172756}}]},{erl_eval,do_apply,5},{erl_eval,expr,5}, 
{lists,foreach,2}]}
