The slab garbage collector uses sched_tick as its time reference, which
is increased every seconds, while the interval is expressed in clock
ticks. Use the proper time reference instead.

The kernel submaps eat most of the available kernel space. Using the
main kernel map for thread stacks sometimes lead to exhaustion when many

Literature about red-black trees vary concerning the cases numbering,
and the implementation doesn't make all of them clearly appear. Remove
