Hi everybody,

    I tried to reduce the IO of bitcoind, and I found '-flushwallet=false'. After trying it, my IO reduced greatly.
    But why 'flushwallet' is true by default? Is there any danger if closing the flush wallet thread?
    I lost all my coins in testnet after one crash with '-flushwallet=false', was this because of no flush wallet thread?
