Back when we had RAC this was a vaguely meaningful thing. Since then it's been a glorified (and confusing) wrapper around xf86BlockSIGIO. Note that the APM and VT switch code are unusual relative to other code that cares about SIGIO state. Most callers push a SIGIO disable to create a critical section for the duration of the caller's stack frame, but those two effectively disable SIGIO after their return and re-enable on their next entry.
