This is what `vim` seems to expect and imo makes way more sense.

This prevents dead lock if read-end does not detect data before blocking
why write-end already notified.

Kernel: Allow open with O_CREAT bypass file permission checks
...
call to open(path, O_CREAT|O_EXCL|O_RDWR, 0444) should open file as
read-write although file is created as read-only on filesystem.

Most software uses urandom instead of random so this allows it work
normally.

I don't know why I had added this. It doesn't seem to be a thing on
either POSIX or linux. This was literally equivalent to EXIST

This prevents calls to write_sectors_impl and all dirty pages are always
kept in RAM.

I have no idea why I did not have this in. All devices were just
constatly spamming interrupts like crazy :D

Kernel: Disable USB Mass Storage writing until I get it fixed
...
This prevented real hw from running for over 10-20 seconds. When first
disk sync happens after 10 secods, USB storage would enter faulty state
and not allow any io operations.
I have no idea what the problem is. If I don't send Reset command to the
USB device writing seems to work fine. I also don't think its part of
the Reset process either as reading works just fine.

Kernel: Fix Thread destruction after sys_exit
...
This had undefined behaviour as Thread's (Processes's) PageTable was
destroyed before Thread had the change to destroy its own stacks that
lived on the PageTable.

If root device is initialized asynchronously it may not be ready when
