The following ld_preload can help in some cases. Mutt has this hack
encoded in for maildir directories, which helps.

It doesn't work very reliable for me.

For some reason, it hangs for me sometimes (doesn't remove any files, rm -rf just stalls), or segfaults.


As most of the ideas here in this thread assume (re)creating a new filesystem from scratch - would perhaps playing with /proc/sys/vm/dirty_ratio and /proc/sys/vm/dirty_background_ratio help a bit?
