Reuse DFT descriptors?

[lhartzman]

I see that the DFT routines require a 'descriptor' to be created dynamically (and later freed).

Can the descriptor be reused by another function, or does each call for the DFT routines require a 'create'/'free' pair?

I'm worried about constant heap requests. Since I'm on MKL 7.2 currently I cannot provide my own 'malloc' function which could use a pre-allocated buffer.

I've discovered that you can reuse the descriptor. One less item to think about.
