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?
2006-08-20	removed block system call	kaashoek
	renumber system calls (run gmake clean!) skeleton for dup system call
2006-08-19	chdir	kaashoek
	cd in shell nits in mkdir, ls, etc.
2006-08-14	start on mkdir	kaashoek
	stat
2006-08-13	link()	rtm

2006-08-12	fix getblk to actually lock the block	rtm

2006-07-15	no more recursive locks	rtm
	wakeup1() assumes you hold proc_table_lock sleep(chan, lock) provides atomic sleep-and-release to wait for condition ugly code in swtch/scheduler to implement new sleep fix lots of bugs in pipes, wait, and exit fix bugs if timer interrupt goes off in schedule() console locks per line, not per byte
2006-07-11	pre-empt both user and kernel, in clock interrupt	rtm
	usertest.c tests pre-emption kill()
2006-07-06	disable all interrupts when acquiring lock	kaashoek
	user program that makes a blocking system call
2006-07-01	swtch saves callee-saved registers	rtm
	swtch idles on per-CPU stack, not on calling process's stack fix pipe bugs usertest.c tests pipes, fork, exit, close

	pipes
2006-06-26	system call arguments	rtm

2006-06-15	sleep, wakeup, wait, exit	rtm

2006-06-15	primitive fork and exit system calls	rtm
