I also suggest watching this video form Dave's EEVBlog about bypass caps, although not exactly your situation, the non-idealities of capacitors that are explained in this video also apply to your problem.

Dave Jones, of EEVblog fame, has made a nice tutorial about bypass capacitors (EEVblog #859).
