I've added a new test that covers a case I discovered during multithreaded testing. For larger files (50000+ reads), ReadParser does not deliver all reads with multiple threads. I'm not exactly sure where this comes from, but the case is covered by an existing test if you give it a larger input file.
Testing output:
This number of reads missed is a function of the cache size given to the constructor [edit: cache size is determined by the khmer config object]. For example, testing with different cache sizes and thread counts:
I probably have a poor understanding of how the caching / buffering is implemented, but it seems to me changing buffer sizes shouldn't affect correctness...
