Alexis, it is a commonly accepted practice at Apache that patches are peer reviewed before being committed
That's not strictly true. It depends on what policy the project is using. Apache supports both Commit-then-Review (CTR) as well as Review-then-Commit (RTC) models. Each has their own advantages and outcomes:
My personal rule of thumb is that if I'm doing some quick, easy bug fux, or some new feature, etc., then simply committing it, then asking for feedback is fine. As devs/committers, we have been granted the commit bit, and we're using SVN, so things can change as needed. On the other hand, if I'm doing something larger, and I want feedback from folks before I put it in SVN (maybe I anticipate not having time to modify it much after that point, or I just feel that getting it right first really matters), then I'll enter into RTC mode and ask for feedback via patches.
Either way is fine, really.
