// Continue to execute interrupted context. The argument is the pointer to part of
// the context structure starting from ES:
// ES, DS, EDI, ESI, EBX, EDX, ECX, EAX, EBP, EIP, CS, EFLAGS, ESP, SS.
// This function is used as substitute to NtContinue. NtContinue hasn't mutual
// exclusion for using context with NtGetContextThread and NtSetContextThread till
// build 717.
// This way seems to be safe enough.
