* process dies/exits. (The kernel assumes responsability over the
* memory at the same time)
*
* As well as the psSharedPBDescKernelMemInfo you must also pass
* a complete list of other meminfos that are integral to the
* shared PB description. (Although the kernel doesn't have direct
* access to the shared PB desc it still needs to be able to
* clean up all the associated resources when it is no longer
* in use.)
*
* If the dissociation fails then all the memory associated with
* the psSharedPBDescKernelMemInfo and all entries in psKernelMemInfos
* will be freed by kernel services! Because of this, you are
* responsible for freeing the corresponding client meminfos _before_
* calling SGXAddSharedPBDescKM.
