Comment 58 for bug 290666

This patch solves the problem. Users should be aware that disabling fsync compromises durability (i.e. system crashes can corrupt your database).
The relevant liferea bug is https://sourceforge.net/tracker/index.php?func=detail&aid=2216604&group_id=87005&atid=581684

I think there is some development going on to circumvent this in future releases by making writes asynchronous.
