2006-09-06	some pipe support in sh	kaashoek
	bug in proc_wait
2006-08-30	complain if no disk 1	rtm
	lots of cleanup
2006-08-29	nits	rtm

2006-08-29	clear killed flag in exit	rtm
	idecref cwd in exit
2006-08-29	prune unneeded panics and debug output	rtm

2006-08-29	i broke sbrk, fix it	rtm

2006-08-29	clean up stale error checks and panics	rtm
	delete unused functions a few comments
2006-08-24	bug in sbrk	kaashoek
	test malloc
2006-08-24	user-level malloc (untested)	kaashoek
	nit in sbrk indirect block fix dup to share fd struct
2006-08-23	i/o redirection in sh	kaashoek
	better parsing of sh commands (copied from jos sh) cat: read from 1 if no args sbrk system call, but untested getpid system call moved locks in keyboard intr, but why do we get intr w. null characters from keyboard?
2006-08-19	chdir	kaashoek
	cd in shell nits in mkdir, ls, etc.
2006-08-15	no more proc[] entry per cpu for idle loop	rtm
	each cpu[] has its own gdt and tss no per-proc gdt or tss, re-write cpu's in scheduler (you win, cliff) main0() switches to cpu[0].mpstack
2006-08-15	commented out code for cwd	kaashoek

2006-08-13	link()	rtm

2006-08-10	interrupts could be recursive since lapic_eoi() called before rti	rtm
	so fast interrupts overflow the kernel stack fix: cli() before lapic_eoi()
2006-08-08	fix race in holding() check in acquire()	rtm
	give cpu1 a TSS and gdt for when it enters scheduler() and a pseudo proc[] entry for each cpu cpu0 waits for each other cpu to start up read() for files
2006-07-29	open()	rtm

2006-07-27	primitive exec	rtm

2006-07-18	prevent longjmp / forkret from writing over tf->edi	rtm

2006-07-17	add ide_lock for sleep	rsc

2006-07-17	standarize on unix-like lowercase struct names	rsc

2006-07-17	add uint and standardize on typedefs instead of unsigned	rsc

2006-07-17	goodbye PushRegs	rsc

2006-07-17	nitpicks	rsc

2006-07-16	Eliminate annoying Pseudodesc structure.	rsc
	Eliminate unnecessary parts of mmu.h.
2006-07-16	standardize on not using foo_ prefix in struct foo	rsc

2006-07-16	Rename fd_reference to more suggestive fd_incref.	rsc
	(Fd_reference sounds like it might just return the ref count.)
2006-07-16	Attempt to clean up newproc somewhat.	rsc
	Also remove all calls to memcpy in favor of memmove, which has defined semantics when the ranges overlap. The fact that memcpy was working in console.c to scroll the screen is not guaranteed by all implementations.
