Her loosing control over the kyuubi is somewhat off of what we have read, also, how would she "regain" control ? Naruto always had Jiraya's seal (witch he handed to Kakashi) and Yamato with his mokuton to repress the Kyuubi's chakra and allow Naruto to quit bijuu mode, Kushina had none of that.

If kushina by any chance would lose control, in her time has Jinchuriki, would be only when the seal would lose it's power over the years and wouldn't be redone.
Naruto transformations, only occur, because Minato intentionally did the seal to allow a small quantity of Kurama's chakra to mix with Naruto's own, so the "hole" in the seal was always there, i don't think that all bijuu's were sealed in their host with the exact same though, so they would only go "wild" when a village intentionally would want the seal to lose it's power in an attempted to gain control over the bijuu (like we see in Bee's past), but in the process the host dies if the bijuu gains the "though of war".
good points but i would like to argue that if kushina ever truly did lose control then it would be dealt with at an earlier stage in the transformation, as in long before the bijuu completely emerges. minato with sealing techniques would most likely be the first method.

it's also good not to forget that kushina could have, for any intentional reason, gone into any stage of tailed beast mode and allowed kyubi to use its power (beast bomb). it's likely minato would be close. what is almost certain is that any beast bomb minato would have witnessed from the kyubi would not be in the context or scenario of an attack on konaha or else it would have been something mentioned already. maybe minato and kushina fought side by side and used the kyubi's power a bit. they could have even been battling another beast or jinchuuriki.
