This. Exactly this is the problem with semi-popular Free Software projects, and what annoys me most with almost-but-not-quite unmaintained projects. It is really no problem if somebody's time is limited. But it is a problem if they don't delegate properly, and thus make it very hard for volunteers to assist them, or to even take over when the time arrives. It's not so much about doing not enough work, it is about preventing others from coordinating their work on it. Unfortunately, many people don't notice that they are actually doing this. They try to review more and more contributions, work starts piling up, but they link their problem is missing time, while it really is missing trust. Also, this transition is much easier when you still have some time. When you arrive at a state where don't have any time at all, it is really hard to perform proper delegation, and one or two (hopefully not too much uncoordinated) forks are they only way for the community to reorganize.
