Review Comment:
If malloc/realloc only be called in non-interrupt context, it could be
replace with spinlock.
Do you have any benchmark to measure the time to select using spinlock or
mutex?
I just interest in why select mutex instead of spinlock.
mutex will call enter_critical_section and it comsumes a lot of time.
