It's the case which I described as the 2nd comment to your
proposal.

1. pg_standby tries to restore a non-existent file
1-1. remove the trigger file
1-2. pg_standby exits with non-zero code
2. the startup process tries to read it from pg_xlog
2-1. it is applied
3. the startup process tries to restore the next file using pg_standby
3-1. pg_standby gets *stuck* since the requested file and trigger file      don't exist.
