The patch from #488 does not solve the problem on my machine. My machine start to stall even if there is still 2GiB of 8GiB RAM free. The menu stalls, if the icons are not loaded and there is heavy io.

It starts faster to stall while executing
dd if=/dev/zero of=t1 bs=1M count=8K (throughput ~48,2MiB/s)
instead of
dd if=/dev/zero of=t1 bs=4K count=2M (throughput ~52,7MiB/s)

The test data is written on the inner part of the disk, while the os is on the outer part. All partitions are ext4.

High fragmentation caused by lvm snapshots, increases this problem.
