What I had in mind was either (a) have a signal like usr1 mean skip to
start of next track and just give up, or (b) putting a limit on how long
in real time will be spent on a track before punting to the next.

These are not mutually exclusive, nor the only useful ways to tackle the
problem. But options to quit after N errors (or try less hard on that
track) and/or do the same after some elapsed clock time might be generally
useful. There are times when I'll settle for close and times when I want
perfect or nothing, and options to do both would be used by me. The harder
any ripping program has to work the less confidence I have in the result.
