Every developer I've talked to has had the same experience with compilation caches as me: they're great. Until one day you waste a couple hours of your time chasing a bug caused by a stale cache. From that point on your trust is shattered, and there's always a little voice in the back of your head when debugging something which says "could this be caused by a stale cache?". And you turn it off again for peace of mind.
