proc.c:
as a consequence of the implementation of proc_kill,
any loop calling sleep should check for p->killed
and be able to break out with an error return.
notes

it is better if you check *before* sleep.

can swap procdump up after proc_kill
and then have proc_exit and proc_wait on same sheet
a few other nits

sched -> switch2scheduler? or just switch?

factor out switching and scheduling code from process code
Various cleanup: - Got rid of dummy proc[0]. Now proc[0] is init. - Added initcode.S to exec /init, so that /init is just a regular binary. - Moved exec out of sysfile to exec.c - Moved code dealing with fs guts (like struct inode) from sysfile.c to fs.c. Code dealing with system call arguments stays in sysfile.c - Refactored directory routines in fs.c; should be simpler. - Changed iget to return *unlocked* inode structure. This solves the lookup-then-use race in namei without introducing deadlocks. It also enabled getting rid of the dummy proc[0].

syscall.c:
cannot convince runoff1 to split the extern lists to fill previous page completely.

pipe.c:
more comments?
comment how functions get called?
sysfile.c:
is the sys_exec picture upside down?
can sys_open and sys_exec be simplified any?
general:
sizeof parens?

saw random sharedfd failure.
why does fdalloc consume reference?
why mkdir and create?
