caused interrupts to be reenabled (due to unlock), which caused a race. The
problems were especially visible on slower machines.
* Relocated free memory parsing to process manager. This saved quite some
code at the kernel level. Text size was reduced by about 650 bytes.
* Removed locks for updating the realtime in the clock's main loop and the
get_uptime function. Interrupts are no longer reentrant, so realtime is
immediately updated.
