Description
As already mentioned in #1344, Atom has described a way to speed up Truecrypt cracking by testing different cascaded ciphers without fully re-calculating the PBKDF2. Will be supported in oclHashcal 1.38. As usual, it's a pretty obvious optimization once you heard of it 😉

We might consider adding it to Jumbo at some point.

Research direction
Start by reading issue #1344 and the linked hashcat forum discussion, which describe the proposed TrueCrypt cascaded-cipher optimization. Determine how that approach applies to John the Ripper Jumbo; done means the optimization is supported without fully recalculating PBKDF2 for each cipher cascade.
