// inside of the exception filter as follows:
// __try {} __except (status=1,EXCEPTION_EXECUTE_HANDLER) { NT_ERROR (status)}
// NT_ERROR(status) - generates uninitialized variable warning and it shouldn't

// Hack-O-Rama. TDI has a fundamental flaw in that it is often impossible
// to determine exactly when a TDI protocol is "done" with a connection
// object. The biggest problem here is that AFD may get a suprious TDI
// indication *after* an abort request has completed. As a temporary work-
// around, whenever an abort request completes, we'll start a timer. AFD
// will defer further processing on the connection until that timer fires.
//
// If the following symbol is defined, then our timer hack is enabled.
// Afd now uses InterlockedCompareExchange to protect itself
//
// #define ENABLE_ABORT_TIMER_HACK 0
//
// The following constant defines the relative time interval (in seconds)
// for the "post abort request complete" timer.
//
// #define AFD_ABORT_TIMER_TIMEOUT_VALUE 5 // seconds
//
// Goodies stolen from other header files.
