exec now uses phys_zero system call to zero bss segments (instead of
...
using phys_copy to copy zeroes there for every kb), which is a big
optimisation in some cases
fixed a bug that was introduced when function keys became notifies

Replaced flagalrm() timers with another technique to check for timeouts.
...
This allowed removing the p_flagarlm timer from the kernel's process table.
Furthermore, I merged p_syncalrm and p_signalrm into p_alarm_timer to save
even more space. Note that processes can no longer have both a signal and
synchronous alarm timer outstanding as of now.

Moved stime, time, times POSIX calls from FS to PM. Removed child time
...
accounting from kernel (now in PM). Large amount of files in this commit
is due to system time problems during development.

Fixed a bug in PM: sending of reply messages didn't check if destination
...
process is still alive. This caused a panic in some situations, e.g., when
all processes are killed on a shutdown.

Improved NOTIFY system: fixed a minor error, ignore pending notifications
...

make it structurally impossible to run out of buffers.

New NOTIFY system call! Queued at kernel. Duplicate messages (with same source
...
and type) are overwritten with newer flags/ arguments. The interface from
within the kernel is lock_notify(). User processes can make a system call with
notify(). NOTIFY fully replaces the old notification mechanism.

New NOTIFY trap (IPC call) to send queued notification messages.
...
The call works. Permission check, restriction of outstanding notifications
to be added. Low level code to make it work from within interrupt handlers
will be added as well.
