'Restricted' in its name. It is not part of the public API. It is designed
for use by kernel code, and has special calling requirements - it should be
called from a critical section, and then a yield performed after it is
called. Also, the call tree makes use of vListInsert() which should normally
not be called from a critical section - so an assumption is made that the list
being inserted into is empty and therefore the insertion will be fast. */
