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

Just a rough idea on this comment:

Would'nt it be possible to start a new thread in a timer callback if we
would introduce a NutThreadCreateAsync()?
The idea is to not directly schedule to the new thread but create a
thread that is added to the queue of runnable threads but without
scheduling.
Would this be possible?

However this would not prevent Philips bug, as the scheduling appears in
the uart write there...

Bye,

Ole
