A failed operand that reads to the end of the stream (an unterminated array, hex string or dictionary) was retried from its next byte, so '[[[[...' read the rest of the stream once per byte: 40 KB of '[' took 24 s in a release build. Unreadable inline-image parameters did the same from each BI. Failed reads now share an allowance of 8 bytes per stream byte (at least 1 MiB); past it a failed operand is skipped whole and an unreadable inline image ends where its parameters stopped reading. Operands with no operator were all held until one arrived; only the last 1024 or so are now kept, the rest counted as skipped.
