1.0.5.55: interrupt safe REFILL-BUFFER/FD
* Check for blocking / wait for new input before touching the stream.
* Check that the SAP is still there after the wait, in case an interrupt
handler or an FD handler closed the stream from under us.
* Wrap the main action in WITHOUT-INTERRUPTS to prevent asynch unwinds
from leaving the stream in an inconsistent state. (Since the read
is going to be non-blocking it should be over soon enough.)
* Arrange to signal errors outside the WITHOUT-INTERRUPTS.
