(replying to myself from another account, sorry for the confusion)
Of course, this mecanism should also flush files immediately or after a fixed delay in the case where no music is currently playing or when the player is shut down (but I guess that's already done in this latter case).
In the case of repeated config file changes, there would be only one access to the hard drive every X seconds, instead of one for each slight change. I'm not sure this would be a major gain since it's not so frequent, but I guess the more Rockbox becomes a PDA like platform the more it will make sense to reduce hard drive accesses to the strict minimum needed. Don't you think ?
