* Ok there is a lot of debugging in the function. This dates from the
* time of the "syscall in kernel mode" bug caused a trash kstack.
* Since fixing that bug this error has never occurred, as expected, and
* thus this debugging code is now redundant and will be removed soonish
*
* I am always hesitant to remove debugging code because as soon as I do
* a new bug shows up and I need it again :-)
