Depends on which function you call. Since we're talking about DOS, I'll
limit myself to 2F/11xx and 2F/12xx. The former depends on the network redirector, the latter on which subfunction. The majority of the 2F/12xx calls are reentrant, but those which perform equivalents of non-reentrant
DOS calls aren't. They get around DOS's non-reentrancy by using a different stack frame, but there's only one alternate stack frame....
