// Special Exception code for RH to communicate to debugger
// RH will raise this exception to communicate managed debug events.
// Exception codes can't use bit 0x10000000, that's reserved by OS.
// NOTE: This is intentionally different than CLR's exception code (0x04242420)
// Perhaps it is because now we are in building 40? Who would know

// The debugger uses this as a sanity check.
// This could be very volatile data that changes between builds.
// NOTE: Again intentionally different than CLR's checksum (0x31415927)
// It doesn't have to be, but if anyone is manually looking at these
// exception payloads I am trying to make it obvious that they aren't
// the same.
