Hi Joaquin,

Yes, the race seems to be real since there are list manipulations without 
locking the list first. Even if these manipulations are done in the context of 
exclusive container operation, like delete, it is possible that other thread 
is changing the same list as result of an iterator related operation, like 
iterator destruction.

Thanks,
Anatoly
