MC-55099save-all fails to ensure player data is saved, lost after power failure
I have a server running locally and a storm was coming in. I heard a clap of thunder and typed /save-all from my client. Literally 5 seconds later, the power failed! My world is in perfect condition, but when I got back into the game, I was naked at my default spawn point. The server console had this to say upon startup:

So I guess I expected save-all to ensure that my world & player data were saved to disk and flushed. Can we add an exec to "sync" for *nix environments to this command?
EDIT: Also, if it's needed, I made a copy of my world after starting up (while the server was running), so I'm guessing that level.dat would have already been overwritten. (Also, the file b/world/region/r.-1.0.mca was modified as it was read, but I would expect that since the server was running.)
