Description
This loads a handle from MP-sysmodule state.
- When the index is <16, the handle is loaded from an array of handles(presumably for each node on the network).
- When the index is 16, the handle is loaded from stateptrother+{someoffset}.
- When the index is >16(accessed via 17 by the user-process normally), the handle is loaded from stateptrother+{someoffsetother}. This is 0x3000-byte sharedmem, the user-process maps it with mypermissions=read-only and otherpermission=DONTCARE.
