completely off-topic, but brian said something that i forgot to repeat, at the time access to source in the libraries, etc. has saved me a lot of time when debugging. i ran into a situation with one of the other libraries, a couple of weeks ago. i was stumped, and thought about submitting a ts request or a bug report, but being able to read through and step through the source helped me solve the problem.
