<braunr> tschwinge: from a quick look, this isn't similar to the external pager mechanism <braunr> it's an additional tool to help userspace application manage internal caches <braunr> it's similar to what is done to reclaim memory from the slab allocator for example <braunr> and it would indeed be a very good thing to have so that e.g. the hurd can build a distributed but completely dynamic dentry-like cache <braunr> i'm actually glad to see someone else thought of using real time signals for this <braunr> i didn't do any research on that subject yet
