As part of unit testing, I've been creating hash tables with very few keys (e.g., making a sshash dictionary for a sequence set with a single super k-mer), frequently triggering this:

unknown file: Failure
C++ exception with description "each partition must contain more than one key: use less partitions" thrown in the test body.

I was wondering if it would be too much trouble to add support for single-element partitions to fix this?
