The "fix" he does is basically turning liferea into a bit more fragile.

What it does is turn the fsync() call into a no-op (no operation) ,   basically making it do nothing.
On Linux, a call to fsync will in general (ext3/4, jfs) flush all applications unwritten data to disk, causing a momentary stall as it waits to return from this.   Basically the slowdown you see is the program repeatedly (far too often, several times per second)  asking for it's data to be written to disk, and waiting around for the system to make sure that it's there.

For something like liferea that's completely bogus behaviour.
