We are reserving a time for impromptu lightning talks at 4pm. There
are two talks already scheduled for tht time, but anyone that has any
proposal up until 4pm of that evening will be able to spend 5 minutes
talking something about LLVM. We have to close at 5pm, so we can only
accommodate another 4-5 ish talks.
