You can create new, independent heaps using $LK,"HeapCtrlInit",A="MN:HeapCtrlInit"$(). Then, use the $LK,"CHeapCtrl",A="MN:CHeapCtrl"$ as the 2nd arg to $LK,"MAlloc",A="MN:MAlloc"$(). See $LK,"HeapLog",A="MN:HeapLog"$() for an example.
Memory alloced by a task will be freed when the task is killed. The $LK,"System Task",A="FF:::/Doc/Glossary.DD,System Task"$ is a task that never dies. It's memory is like kernel memory in other operating systems. See $LK,"SysCAlloc",A="MN:SysCAlloc"$(), $LK,"SysMAlloc",A="MN:SysMAlloc"$(), $LK,"SysMAllocIdent",A="MN:SysMAllocIdent"$() and $LK,"SysStrNew",A="MN:SysStrNew"$().

All of the regular page tables are marked, "cached". When accessing hardware, however, you need uncached page table. The lowest 4Gig addresses have an alias to access hardware located toward the top of mapped space, $FG,2$0x$TX,"01D7800000",D="DD_UNCACHED_ALIAS"$$FG$. See $LK,"dev.uncached_alias",A="FF:::/Kernel/MultiProc.CC,dev.uncached_alias"$.
