shared with the kernel, mapped into kernel address space; kernel is notified of its location. kernel segment size is increased to make it fit. - map in kernel and other processes that don't have their own page table using single 4MB (global) mapping. - new sanity check facility: objects that are allocated with the slab allocator are, when running with sanity checking on, marked readonly until they are explicitly unlocked using the USE() macro. - another sanity check facility: collect all uses of memory and see if they don't overlap with (a) eachother and (b) free memory - own munmap() and munmap_text() functions. - exec() recovers from out-of-memory conditions properly now; this solves some weird exec() behaviour - chew off memory from the same side of the chunk as where we start scanning, solving some memory fragmentation issues - use avl trees for freelist and phys_ranges in regions - implement most useful part of munmap() - remap() stuff is GQ's for shared memory
