Yesterday I closed about 20 tickets in Module::Build without writing any code. Some of them had been fixed and never checked-off, others were duplicates and several were not bugs.
Of the 11 non-wishlist bugs in the queue, only 5 are known issues, the rest are probably fixed, but need to be verified. When a queue gets too long, the only way to clear it out is to sit down and play historian for a day (and it was a long day.)
