       patch
     <braunr> (more kernel memory, thus more physical memory - up to 1.8 GiB -
       but then, less user memory)

+    <nlightnfotis> braunr: quick question, what memory allocation algorithms
+      does the Mach use? I know it uses slab allocation, so I can guess buddy
+      allocators too?
+    <braunr> no
+    <braunr> slab allocator for kernel memory (allocation of buffers used by
+      the kernel itself)
+    <braunr> a simple freelist for physical pages
+    <braunr> and a custom allocator based on a red-black tree, a linked list
+      and a hint for virtual memory
+    <braunr> (which is practically the same in all BSD variants)
+    <braunr> and linux does something very close too
