Non-zero return value from restore_command doesn't mean end-of-recovery, 
it means file-not-found. The server will try to open the WAL file from 
pg_xlog if it's not found in archive (= restore_command returned 
non-zero). If it's found in pg_xlog, it will then ask for the next WAL 
file from the archive again. And on top of that, the server will ask for 
history files until it finds one that doesn't exist to figure out the 
new timeline.
