Cache compiled kernels

[bmerry]

Currently each sorter object recompiles the program, but sometimes it may be useful to have multiple sorters with the same parameters so that they can operate in parallel. Either

• implement transparent caching; or
• allow sorters to be cloned, which copies a ref to the program; or
• separate the data-independent parts into separate classes

The kernels are cached on disk, but it would still be useful to have an in-memory cache to avoid making OS calls.
