Did you have to clear this with your university/advisor? AFAIK, my university has copyright on code I produce on paid time or using university facilities/equipment, which covers my research and even a good chunk of my homework.

meaning that what I wrote only really serves to glue a bunch of completely closed algorithms together

This is consistent with what I've run across. It seems a lot of research revolves around modifications to an existing system, but in CS, it seems the established code base is more likely to be open source (e.g. Jikes RVM) or be proprietary but still have source code readily available (e.g. SimpleScalar).
