my next task is the elimination of the Giant lock for proper SMP support.

I added some subtasks:

Use one lookup tree per-thread for the POSIX keys

Unify thread cancel/join and delete

Fix CPU time used for threads on SMP

Avoid home-grown condition variable implementation in the Classic Regions

Remove internal mutex objects

Protect time of day changes by a mutex

Use an ISR lock to protect the state of Classic Rate Monotonic objects
