Here's what Helgrind says about (some of) the failures I see. This may be fun and interesting to someone who's read and understands the code (who is not me). There are a lot of similarities; it looks like there's one lock you need to hold at one point you're not holding. The error message about unmapped memory worries me; the GDB backtraces make me think that there's something wrong when a thread tries to find a function in libparrot. Yergh.
