The function of this syscall is not yet known in detail. Under normal circumstances it shouldn't be invoked.
The meaning of the parameter is not yet known.
This syscall claims some kind of internal handle, which is a limited resource. It is not clear yet, how to properly release the handle, or even if it can be released at all. Simon Lothar's document indicates that calling it is only necessary if an add-in-prototype is run from RAM.
