// and writes to general purpose registers to the GS. (note: I'm pretty sure this includes
// direct GS and GSreg accesses, as well as those coming through the GIFpath -- but that
// behavior isn't confirmed yet). Privlidged writes are still active.
//
// Ignorance continues until the SIGNAL bit in CSR is manually cleared by the EE. And here's
// the tricky part: the interrupt from the second SIGNAL is still pending, and should be
// raised once the EE has reset the *IMR* mask for SIGNAL -- meaning setting the bit to 1
