[En-Nut-Discussion] NutThreadRemoveQueue clears runQueue to NULL

[Nathan Moore]

Years ago I considered making a test version of Nut/OS that did away with
the idle thread
and just handled an empty run queue in the scheduler by busy looping on the
thread queue
until it quit being empty.

The reasons for this were to free up the memory that the idle thread
requires and to get away
from the possibility of killing the idle thread (by killing it for good).

In the end I never got around to doing this, though.
