Actually, it is just an fs-specific thing. It happens to be specific to almost most of the common) filesystems that Linux supports, that's all :)
Has Reiser hopes to get a reiserfs patch against 2.3 out sometime this week (a new 2.2 patch is available already). Perhaps if you try that you may not see such misbehaviour.
I suspect that you see it more with the dcache because it will incur fewer blocking operations during the readdir/stat syscalls. 2.3 has a lot less filesystem operation serialised, so you may see significant improvements there.
Matthew.
