Mac SNetDestroy: BOOL __cdecl (void)
There are no stack argument reads ([EBP+n] never appears in 0x00019897-0x00019a46) and no incoming ECX/EDX use. Under the SNet critical section it tears down the provider and connections, then MOV EAX,1 (0x00019a3a) / RET. This is the Storm subsystem Destroy contract; StormDestroy calls it at 0x0000970a.
