Heap sort is now more close to gnulibc++ version. This is just more
simplified version.

Second part was kinda weird. You are supposted to assume something

Now that processes can only die in known spots, we can be sure they
are not holding any locks. This allows much more performant locking.

Kernel: Rework all signal code
...
Signal handling code was way too complex. Now everything is
simplified and there is no need for ThreadBlockers.
Only complication that this patch includes is that blocking syscalls
have to manually be made interruptable by signal. There might be some
clever solution to combat this is make this happen automatically.

My quick fix for fgets wrote non-nullterminated newline if size was

POSIX doesn't specify what happens if size == 0, so I do the same as
glibc and return NULL without setting errno.
