Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

Sure this last bit is intentional? The local-io-error handler may not
even ever be invoked (you'd have to have disk { on-io-error
call-local-io-error; }" for it to ever fire), but most people prefer
to detach on I/O error.
